You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest hundredth.

The probability of not spinning a red, flipping tails, then not spinning an even number is?

Answer:

Just by simply adding the two quantities you can get the net change. $67.12 +(addition sign because we want the net change) $2.56= $69.68. The last number is the net change!

Answer:
(2)/(9)

Explanation:

From the given spinner, the probability of spinning not red ( i.e spinning blue, yellow)is given by :-


\text{P(not red)}=(2)/(3)

The probability of not spinning an even number ( i.e spinning 1, 3) is given by :-


\text{P(not even)}=(2)/(3)

Also, the probability of getting a tail when flipping a unbiased coin =
P(T)=(1)/(2)

Since all the events are independent , thus the probability of not spinning a red, flipping tails, then not spinning an even number will be:-


\text{P(not red)}*\text{P(not even)}* P(T)\\\\=(2)/(3)*(2)/(3)*(1)/(2)\\\\=(2)/(9)
