Question

Create a probability model for the outcome of performing 2 spins. What is the probability of NOT landing on yellow or red at all?

Answer 1

Using the concept of probability, the probability of not landing on yellow or red at all is 1/4.

Creating a square model of the two spins :

• Red(R) ; Blue(B) ; Green(G) ; Yellow(Y)

___ R ___ B ___ G ___ Y

R_ RR __ RB __ RG __ RY

B_ BR __ BB __ BG __ BY

G_ GR __GB __ GG __GY

Y_ YR __ YB __ YG __ YY

• Sample space = 4² = 16

Combinations without red and yellow :

• {BB, BG, GB, GG}
• Number of selections without red or yellow = 4

Recall :

• Probability = required outcome / Total possible outcomes

P(without Red or Yellow) = 4/16 = 1/4

Hence, the probability of not landing on yellow or red at all is 1/4.
