A box has two coins. One has two heads and the other is a fair coin with one head and one tail. Now you flip both coins at the same time.
a.) How many sample points are there in the sample space? List all the sample points.
b.) What is the probability that you come up with two heads?
Homework Answers
a) For first coin, we have only one choice and for second coin, we have two choices. So,
Number of sample points = 1*2 = 2
Sample points will be:
{HH, HT}
b) P(Two heads)
= P(HH)
= 1/2

Suppose there are two coins. One is a standard fair coin, so that P(heads)=0.50. The other one is a two-sided coin, so that P(heads)=1. You draw one of the two coins at random and toss it. It results in heads. Given that observation... (a) Compute the probability that you have selected a fair coin. (1pt) (b) What is the probability that the next toss will result in heads too? (1pt) (c) If the next toss results in heads as well,...

A box contains four coins. Three of the coins are fair, but one of them is biased, with P(11) = ? (where 11 is the event of flipping heads). You take a coin from the box and flip it. It comes up heads. What is the probability that you have flipped the biased coin?

You have 5 coins, four of which are fair coins, i.e. P(H)=P(T)= 0.5, and the other of which is a two headed coin, i.e. both sides have a head. Suppose you select a coin at random and flip in 3 times, getting all heads. If you flip the coin again, what is the probability it will be heads?

Franklin has three coins, two fair coins (head on one side and tail on the other side) and one two-headed coin. 1) He randomly picks one, flips it and gets a head. What is the probability that the coin is a fair one? 2) He randomly picks one, flips it twice. Compute the probability that he gets two tails. 3) He randomly picks one and flips it twice. Suppose B stands for the event that the first result is head, and...
