To determine the probability.

Answer to Problem 36STP

Probability is $\frac{2}{3}$ or 66.7%

Explanation of Solution

Given information :

  

Total possibilities are 6.

We have to determine the probability that a number less than 3 or an odd number shows on top.

Probability that a number less than 3 shows on top is $\frac{2}{6}$ (favorable outcomes are 1, 2 only)

Probability that an odd number showson top is $\frac{3}{6}$ (favorable outcomes are 1, 3, 5)

Now,

P(less than 3 or odd) = P(less than 3) + P(odd) − P(less than 3 and odd)

P(less than 3 or odd) $=\frac{2}{6}+\frac{3}{6}-\frac{1}{6}=\frac{2}{3}$ or 66.7%
