Question

You spin the spinner twice what is the probability of landing on a number greater than 8 and then landing on a number greater than 7

Answer 1

Given,

The number of section in the spinner is 3.

Required:

The probability of landing on number greater than 8 and then number greater than 7.

The probability of landing on number greater than 8.

`P(number\text{ greater than 8\rparen=}(1)/(3)`

The probability of landing on number greater than 7.

`P(number\text{ greater than 7\rparen=}(2)/(3)`

The probability of number landing on number greater than 8 then greater than 7.

`\begin{gathered} P(more\text{ than 8 and 7\rparen=}(1)/(3)*(2)/(3) \\ =(2)/(9) \end{gathered}`

Hence, the probability is 2/9.
