Question

Its just the circled questions. Please help. Thanks in advance!!

Step 1

Problems related to probability of events when 10 coins are tossed (flipped) , independently

Step 2

a) We may represent each of the 10 tosses by H (head) orT (tail). So each experiment can be described as a sequence of H or T (randomly) of length 10. So the total number of outcomes is 2^10=1024. (as each of the 10 places can be filled in 2 ways )

Step 3

(b) Denote the probability of Head as c; then the probability of 0-heads in a 10 -f...
