Probability is the likelihood or chance that an event will occur. If the probability of the spinner showing an even number if the odds against a spinner showing an even number are 3:8 is 8/11

What is probability?

Probability is the likelihood or chance that an event will occur. The formula for calculating probability is expressed as:

Probability = expected/total outcome

If the odds against a spinner showing an even number are 3:8, the total number of spins is 11 spins

From the ratio

Number of odd spin = 3

Number of even spin = 8

Find the probability of spinning even

pr(even spin) = 8/11

Hence the probability of the spinner showing an even number if the odds against a spinner showing an even number are 3:8 is 8/11
