Question

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 1

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

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)`
