What is the probability of getting either blue or green on a spinner that is 3/10 greens and 1/5 blue?

Semmy [17]

Answer:

1/2 or 0.50

Step-by-step explanation:

To find the probability of getting either blue or green on a spinner, we must add both probabilities together.

$\frac{3}{10}+\frac{1}{5} = ?$

To make adding our two fractions easier, we need to make sure they have like denominators.

$\frac{1*2}{5*2} =\frac{2}{10}$

Now that the denominators of our probabilities are the same, we can add them together to get our answer.

$\frac{3}{10} +\frac{2}{10}=\frac{5}{10}$

$\frac{5}{10} =\frac{1}{2}$ or $0.50$

Answer:

We conclude that the simplified expression is:

$0.10\left(7l\:+\:2s\right)=0.7l+0.2s$

Step-by-step explanation:

Given the expression

$0.10\left(7l\:+\:2s\right)$

Apply the distributive law: a(b+c) = ab+ac

a = 0.1, b = 7l, c = 2s

$0.10\left(7l\:+\:2s\right)=0.1\cdot \:7l+0.1\cdot \:2s$

$=7\cdot \:0.1l+2\cdot \:0.1s$

$=0.7l+0.2s$

Therefore, we conclude that the simplified expression is:

$0.10\left(7l\:+\:2s\right)=0.7l+0.2s$
