Students in Mr. Jacob's class used a number
cube with sides numbered 1 through 6 and a spinner with 4 even-numbered and 4 odd-numbered sections. For each trial, they recorded whether the outcomes for the cube and the spinner were even or odd.


Based on the data in the table, which is closest to the number of times the next 50 trials should result in both the cube and the spinner being even?

A 12

B 25

C 48

D 50

Answer:

25.

Step-by-step explanation:

the ratio from even to odd is equal. a half chance of getting even 3:6 & 4:8 [ theres 3 even #s on the cube, 3 odds #s on the cube] vice VERSA!! for either even or odd roll. so out of 50, half of 50 is 25. there's a 1:2 chance of even(or in whatever case) 1:2 = 25:50
