Answers
Given : Brian spins a fair spinner numbered 1 to 5 and flips a fair coin.
To Find : What is the probability of obtaining a 2 and a head?
Solution:
Brian spins a fair spinner numbered 1 to 5
Total possible outcomes = 5
flips a fair coin.
Possible outcomes = 2
Total Possible outcomes = 5 x 2 = 10
n(S) = 10
E = probability of obtaining a 2 and a head = ( 2 , H)
n(E) = 1
probability of obtaining a 2 and a head = n(E)/n(S)
= 1/10
probability of obtaining a 2 and a head = 1/10
