Question

The odds against an event are 7 to 1. find the probability that the event will occur.

Answer 1

$\dfrac{1}{1+7}=\dfrac{1}{8}=12.5\%$

Answer 2

The probability that the event would occur is 0.125

How to determine the probability?

The odds against is given as:

Odds against = 7 : 1

The probability that the event would occur is then calculated as:

P = 1/(1 + 7)

Evaluate the sum

P = 1/8

Evaluate the quotient

P = 0.125

Hence, the probability that the event would occur is 0.125
