An experiment has three possible mutually exclusive outcomes, A, B, or C. The odds of A occurring are 3 to 10 and the

Arte-miy333 [17]

Using the relation between odds and probability, it is found that:

1. P(C) = 17/39.

2. The odds of C occurring are 17 to 22.

<h3>What is a probability and what is an odd?</h3>

A probability is given by the number of desired outcomes divided by the number of total outcomes.

An odd is the number of desired outcomes divided by the number of non-desired outcomes.

Considering the odds, the probabilities for A and B are given as follows:

P(A) = 3/(3 + 10) = 3/13.

P(B) = 1/(1 + 2) = 1/3.

The sum of all probabilities is of 1, hence the probability of C is found as follows:

$\frac{3}{13} + \frac{1}{3} + P(C) = 1$

$\frac{9 + 13 + 39P(C)}{39} = 1$

39P(C) = 17

P(C) = 17/39.

17 desired outcomes and 39 - 17 = 22 non-desired, hence:

The odds of C occurring are 17 to 22.
