asic Statistics Bag 1 contains 5 red balls and 3 black balls. Bag 2 contains a red balls and 1 black ball. Bag 3 contains 4 red balls and 2 black balls. If a bag is selected at random and a ball is drawn, find the probability it will be red (5 marks)
An urn contains 8 balls: 4 orange, 3 red, and 1 green. Two balls are selected without replacement. Find: a) P(both balls are orange) = ______________ b) P(both balls are green) = _______________ c) P(both balls are red) = ___________________ d) P(the first ball is orange and the second is green) =______________ e) P(the first ball is red and the second is orange) =________________ f) P(one is orange and one is green in any order) =________________
3- Two balls are drawn from a bag containing 3 white balls and 4 red balls. If the first ball is replaced before the second is drawn, what is the probability that a. Both balls are red? b. Both balls are white? c. The first ball is red and the second ball is white? d. One of the balls is black? 4- A bag contains 7 coins, of which 4 are fair; the remaining coin has a head on both...
A bag contains 6 blue balls, 2 red balls and 1 black ball. If two are selected at random, find the probability of obtaining the black ball.
Bag A contains two balls, one red and one white and Bag B contains two white balls. A bag is selected at random, and one ball is taken at random from that bag. If the selected ball is white, what is the probability that the other ball in the bag is red? Give your answer as a fraction in its simplest form.
A golf ball is selected at random from a golf bag. If the golf bag contains 1 green balls,6 brown balls, and 8 orange balls, find the probability of the following event. the golf ball is green or brown.
There are 1 0 balls in a bag, 4 red balls, 2 black balls, and 4 yellow balls. Every time you can pick one ball without replacement. Now you pick 2 times. (1) How likely you will have 2 black ball ls if you pick 2 times. (2) How likely you will have one red ball and one yellow ball if you pick 2 times. (3) How likely you will have at least one yellow balls. Can someone explain it...
Two balls are drawn, without replacement, from a bag containing 13 red balls numbered 1−13 and 4 white balls numbered 14−17. (Enter your probabilities as fractions.) (a) What is the probability that the second ball is red, given that the first ball is white? (b) What is the probability that both balls are even-numbered? (c) What is the probability that the first ball is red and even-numbered and the second ball is even-numbered?
1) Suppose a bag contains 50 red balls, 30 green balls and 20 blue balls. (a) If you draw 2 balls at random without replacement, what is the probability that they are red and green? (b) If you draw 3 balls at random without replacement, what is the probability that all 3 are of different colour? (c) If you draw 3 balls at random without replacement, what is the probability that you draw at least 1 red ball? 2) A...
