Question

Use the table on the left to help you answer a) What is the probability of selecting a pair of red shorts?b) What is the probability of selecting shirts or a white clothing item?

Answer 1

`\text{probability}=\frac{\text{ number of favorable cases}}{total\text{ number of cases}}`
`\text{ P(red shorts)=}(8)/(4+6+2+8+3+7)=(8)/(30)=(4)/(15)`
`\text{ P(shirt or white)=}(4+6+2+7)/(4+6+2+8+3+7)=(19)/(30)`

(Notice that, in the last case, there are 2 cases that satisfy both criteria at the same time, that is, there are 2 white shirts; you don't have to add it twice, that is why in the numerator there is only one 2)
