If 10 coins are to be flipped and the first 5 all come up heads, what is the probability that exactly 3 more heads will be flipped?

A

0.0439

B

0.1172

C

0.125

D

0.3125

Text Solution

Verified by Experts

The correct Answer is:
D
The first 5 flips have no effect on the next 5 flips, so the problem becomes "what is the probability of getting exactly 3 heads in 5 flips of a coin?" `((5)/(3))=10` outcomes contain 3 heads out of a total of `2^5=32` possible outcomes. P(3H)=`5/(16)~~0.3125. [22]
