NeTakaya

Answer:

30%

Step-by-step explanation:

A family is trying to pick from different shades of paint for their living room. They have narrowed it down to 10 colors: 3 different blues and 7 different greens. The family decides to just randomly select a color from these. What is the probability they will pick a shade of blue? Choose the answer in percent form. Question 3 options: 50% 100% 70% 30%

First, we need to convert the probability of picking a blue shade into a fraction.

= 3/10

Since this is by 10, we need to times 0.3 (numerator) by 10 (the number of outcomes) Whatever you do to the numerator, you do to the denominator. This means that you also times 10 by 10

This gives you 30/100

Since a percentage is out of 100, you don't need to change anything, just take away the 100 and put a percentage sign.

=30%

Answer:

The probability of hitting an odd number three times is 3.375 times more than the probability of hitting an even number three times..

Step-by-step explanation:

Probability of hitting an odd number = 3/5

Probability of hitting an odd number = 2/5

Probability of hitting an odd number three times = (3/5)^3

Probability of hitting an odd number three times = (2/5)^3

Now divide (3/5)^3 by  (2/5)^3 we get:

(3/5)^3 / (2/5)^3

(3)^3/(2)^3

27/8 = 3.375

The probability of hitting an odd number three times is 3.375 times more than the probability of hitting an even number three times..
