Question

If each of the regions in each spinner at right is the same size,what is the probability of spinning each spinner and getting a green t-shirl? 1.Determine both possibilities: P(green) = 1/4 and P(1-shirt) = 1/3 2.Since you are intersed in the compound event of both green and a 1-shirt, multiply both probabilities: 1/4,1/3 = 1/12 The probability of spinning a green t-shirt is 1/12:p(green t-shirt) = 1/12 Assume in each of the problems below that events are independent of each other.One die.numbered 1, 2, 3,4,5. and 6, is rolled.What is the probability of rolling l or a 6? 2.Mary is playing a game is which she rolls one die and spinsa spinner,What is the probabitiy she will get bork3.A spinner is divided into eight equal seetionus the sections are numbered 1, 2, 3,4,5,6,7. and 8.What is the probability of spinning a 2.3 or a 4? 4.Patty has a box of 12 colored pencils. There are 2 blue.I black,I gray.3 gray.3red,2green,1orange,1purple,and 1 yellow in the box.Prty coloses her eyes and chooses one pencil. she is hoping to choose a green or a red.What is the probability she will get her wih? 5.Use the spinners at right to tell paul what his chaoces are of getting the silver he wants. 6. On the way to school. the school but must go through two traffic signals. The first light is green for 25 seconds out of each minute, and the second light is freer for 35 seconds out of each minute. What is the probability that both lights will be green on the was to school?

Explanation / Answer

1) we have rolled a dice

the sample space will = {1,2,3,4,5,6)

these are the values which can come when we roll a dice single time

we need to find the probability that either 1 comes or 6 comes when we roll a dice

therefore the probability = 2/6 = 0.333 [ here we put 2 because we are taking 2 elements from the sample space and there are total 6 elements in the sample space]

hence the answer = 0.333
