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

=

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
