Question

Using this number cube and spinner, which simulation would help you answer this question? Over the past 50 50 years, records for one northwest city show that rain fell on the first day of spring 13 1 3 of the time. If you choose a year at random, what are the chances that the first day of spring will be a rainy Wednesday?

Answer 1

if your on imagine math its a

Explanation:

Answer 2

`Probability=(1)/(21)\\\\Percentage\ chances\approx 4.76\%`

Explanation:

Probability: Probability of an event to occur is given by:

`P=(Number\ Favourable\ outcomes)/(Number\ of\ total\ outcomes)`

Probability of Wednesday:

`Total\ number\ of\ outcomes=7(as\ there\ are\ 7\ days\ in\ a\ week)\\\\Favourable\ outcomes=1\ (only\ Wednesday)\\\\P(Wednesday)=(Number\ of\ favourable\ outcomes)/(Number\ of\ total\ outcomes)\\\\P(Wednesday)=(1)/(7)`

Probability of first day rainy:

`Let\ probability=P\\\\It\ is\ given\ that\ (1)/(3)\ times\ the\ first\ day\ is\ rainy.\\\\P=(1)/(3)`

Probability that first day is rainy Wednesday:

Let probability
`=P`

Since these two events are independent

`P=P(Wednesday)* P(rainy)\\\\P=(1)/(7)* (1)/(3)\\\\P=(1)/(21)`

Percentage chances of rainy Wednesday
`=(1)/(21)* 100\approx4.76\%`
