An urn contains 100 marbles. Fifty are purple, ten are green, fifteen are red, and twenty five are orange. Two marbles are drawn at random one after another with replacement. Calculate each probability. a. P(purple and orange) b) P(green and green)

To find A you would first take the 50 purple and 25 orange and combine them, this would give you 75 you would then put that over a 100 since there’s a 100 marbles total so 75/100=.75 which is 75% you would do the same for the green 10/100=.1 so a) 75% and b).1% or 10%

Probability of drawing a purple and orange marble one after another = [tex]\frac{1}{8}[/tex]

Probability of drawing a green and green marble one after another = [tex]\frac{1}{100}[/tex]

What is Probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Probability of drawing a purple and orange marble one after another = Probability of drawing a purple marble * Probability of drawing an orange marble = [tex]\frac{50}{100}*\frac{25}{100} = \frac{1}{8}[/tex]

Probability of drawing a green and green marble one after another = Probability of drawing a green marble * Probability of drawing an green marble = [tex]\frac{10}{100}*\frac{10}{100} = \frac{1}{100}[/tex]
