studies and passed: 26

did not study and passes: 1

did not pass and study: 3

did not pass and did not study: 2

Step-by-step explanation:

in total he had 32 classes. if he studied for 27 in total, he must have not studied for 5 because 27+5 is 32. He passed and studied for 26 so he didnt study and passed one which equals 27. He studied but sis not pass for 3 classes and did not study and did not pass for 2. that gives you 5. 5+ 27=32.

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
