You have a jar of marbles with 7 red, 12 blue, 6 yellow, and 9 white. What is the probability of selecting a marble that is not

Schach [20]

Answer:

The probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102

Step-by-step explanation:

Number of red marbles = 7

Number of blue marbles = 12

Number of yellow marbles = 6

Number of white marbles = 9

Total marbles = 7+12+6+9=34

Probability of selecting red marble = $\frac{7}{34}$

Probability of selecting no red marble = $1-\frac{7}{34}=\frac{27}{34}$

Now replacing it one marble is drawn again

So, Probability of getting white marble $=\frac{9}{34}$

So,the probability of selecting a marble that is not red, replacing it and then one that is white = $\frac{27}{34} \times \frac{9}{34}=0.2102$

Hence the probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102

Caroline rolls a fair dice 480 times. How many times would Caroline expect to roll a six?

Gnom [1K]

A fair die has 6 sides so a 1/6 chance for each number
So divide 480/6= 80
80 times for each number, 80 for 6
