An urn contains 10 marbles: 4 red, 3 white, 2 blue, and 1 orange. (4 points) (a) what is the probability of drawing a marble that is red or white? (b) what is the probability of drawing a marble that is neither red nor white? (c) what is the probability of drawing a pair of marbles, one red and one white at the same time? (d) what is the probability of drawing a pair of marbles, one blue and one orange at the same time?

a) 0.70

b) 0.30

c) 12/45 =4/15

d) 2/45

Step-by-step explanation:

a) Prob of drawing a marble red or white = No of red and white marbles/total marbles

= 7/10 = 0.70

b)  Prob of drawing a marble neither red nor white = 1-7/10 = 0.30

c)  Prob of drawing two marble one red and one  white at the same time

=

d) Prob of drawing two marble one blue and orange  white at the same time

=

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
