Q1Discrete Random VariablesFree sample
A fair spinner with 5 sides numbered 1, 2, 3, 4, 5 is spun repeatedly. The score on each spin is the number on the side on which the spinner lands.
(a)1M
Find the probability that a score of 3 is obtained for the first time on the 8th spin.
(b)2M
Find the probability that fewer than 6 spins are required to obtain a score of 3 for the first time.
