Children 122 146 268
Adults 183 219 402
Total 305 365 670

The two-way table is an illustration of probability, and the value of P(Adult|Second run) is 0.600

How to determine the probability?

The probability to calculate is given as: P(Adult|Second run)

This means:

The probability that an Adult is selected given that the adult runs the second run

The formula to solve this is:

P(Adult|Second run) = n(Adult and Second run)/n(Second run)

From the table, we have:

n(Adult and Second run) = 219

n(Second run) = 365

So, we have:

P(Adult|Second run) = 219/365


P(Adult|Second run) = 0.600

Hence, the value of P(Adult|Second run) is 0.600
