Question

Create the sample space for tossing 4 coins at one time.

Using the sample space for tossing 4 coins, what is the probability of tossing only one head on a toss?

Answer 1

solution:- Let the 4 coing tossing at one time. The sample space. for tossing 4 coing is as below. s2 = {HHHH, HHHT, HHTH, HTHH, THHH, HTHT, TT HI, HTTH, HHTI,THTH, THHT, THTT, HTTT, TT HT, TTTH, TTTT? Here, number of outcomes in an is . | n(A) = 16 | Let A be the event that tossing of only one head on a toss · There fore possible outcomes are:- ... A = {THTT, HTTT, TTHT, TTTH} - and n(A) = 4 i probability of toosing only one head on a toss.is. denoted by PCA) and is given as : - :: PCA) = hy = feca) =
