Q:

WILL GIVE A BRAINLESTA spinner contains four equally shaded areas, as shown below.Louise spins the spinner twice. Which probabilities are correct? Check all that apply.P(both green) = 1/16P(both blue) =1/4 P(first green and then blue) = 1/6P(first orange and then blue) = 1/8P(first orange and then green) = 1/4

Accepted Solution

A:
Answer:Options 1, 2, 4 Step-by-step explanation:For option 1. P(both green) P(one green) = 1/4P(second green) = 1/4P(both green) = (1/4)(1/4) = 1/16For option 2. P(both blue)P(one blue) = 2/4 = 1/2P(second blue) = 2/4 = 1/2P(both blue) = (1/2)(1/2) = 1/4For option 3. P(first green and then blue)P(first green) = 1/4P(second blue) = 2/4 = 1/2P(first green and then blue) = (1/4)(1/2) = 1/8For option 4. P(first orange then blue)P(first orange) = 1/4P(second blue) = 2/4 = 1/2P(first orange then blue) = (1/4)(1/2)=1/8For option 5. P(first orange then green) P(first orange) = 1/4P(second green) = 1/4 P(first orange then green) = (1/4)(1/4) = 1/16Option 1, 2, 4 are correct.
