you spin the spinner flip a coin then spin the spinner again find the probability of the compound event. The probability of spinning a for flipping heads than is?

Given:

Numbers in the spinner = 1 to 9 ==> 9 numbers

Possibilities in a coin == Head and tail

Given that you spin the spinner flip a coin then spin the spinner again, let's find the probability of spinning a 4, flipping head, then spinning a 7.

We have the following:

• Probability of spinning a 4:


P(4)=(1)/(9)

• Probability of flipping head:


P(head)=(1)/(2)

• Probability of spinning a 7:


P(7)=(1)/(9)

Hence, we have:


\begin{gathered} P=P(4)*P(head)*P(9) \\ \\ P=(1)/(9)*(1)/(2)*(1)/(9) \\ \\ P=(1*1*1)/(9*2*9) \\ \\ P=(1)/(162) \end{gathered}

Therefore, the probability is:


(1)/(162)

ANSWER:


(1)/(162)
