Answer:
P(blue then red)=5/169
Step-by-step explanation:
the probability of picking the blue is 4/26 it's replaced so the total jellybeans doesn't change therefore the sample space doesn't change. the probability of picking a red is 5/26
to find the probability of picking them in that order, you multiply the two together
(4/26)x(5/26)=20/676
reducing that we get:
P(blue then red)=5/169
Answer:
684 ft^2
Step-by-step explanation:
You can find the area of the middle rectangle by using:
You can find the area of a triangle by using:
Triangle 1: A=90
Triangle 2: A=72
2(72+90)+360
324+360
684
Answer:
10 ounces
Step-by-step explanation:
Divide both sides by 10. You get 0.556 oz for 1 oz. For the other, it is 0.66. Thus, the 10 oz is better.
Answer:
1?
Step-by-step explanation:
am not sure sorry if am wrong
Probability of choosing a black fly = 30/100 = 0.3
Probability of choosing a grey fly = 70/100 = 0.7
So, probability of choosing 2 grey flies = 0.7*0.7 = 0.49
