Will Fan And Medal ! HELP A coin is tossed and a spinner numbered 1 to 7 is spun. What is the probability of getting an even number and tails?

OpenStudy (math_man21):

31/2 over 7

OpenStudy (reneeshumpert):

Wait huh?

OpenStudy (kropot72):

Do you want step by step help to solve this?

OpenStudy (reneeshumpert):

Yeah so I can know how to do it

OpenStudy (kropot72):

Good. The first step is to decide whether or not the outcomes are independent. Will the outcome of the coin toss have any effect on the outcome of spinning the spinner?

OpenStudy (reneeshumpert):

Nope, two different scenarios

OpenStudy (kropot72):

Correct. Therefore we need to find the probability of an even number and the probability of tails. Then these two values of probability are multiplied to find the required probability of the intersection of tails and an even number. What is the probability of an even number?

OpenStudy (reneeshumpert):

Okay let me make a table really quick

OpenStudy (kropot72):

Just find how many even numbers are on the spinner, then divide that number by 7.
