Question

Quizplus · Accepted Answer

The probability of not hitting a red in one spin is the probability of hitting either a black or a green, which is 20/38 (since there are 18 black and 2 green slots out of a total of 38 slots). The probability of not hitting a red in 4 consecutive spins is (20/38)^4. To find the probability of hitting at least one red in 4 spins, we subtract this value from 1. So, 1 - (20/38)^4 ≈ 0.9048.
