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 $0.50$

EleoNora [17]

this is a binomial problem: p = 0.7 and q = 0.3

a) (0.7)^6

b) (6C4)(0.7)^4(0.3)^2

c) Pr ( at least 4) = Pr(4) + Pr(5) + Pr(6) = (6C5)(0.7)^5(0.3) + (0.7)^6

d) Pr (no more than 4) = 1 - Pr(at least 4) = 1 - (answer from c)
