Answer:
7/27 ≈ 25.9%
Step-by-step explanation:
"At most one" means either exactly 0 or exactly 1.
P(at most 1) = P(0) + P(1)
Using binomial probability:
P(r) = nCr pʳ qⁿ⁻ʳ
P(0) = ₃C₀ (⅔)⁰ (⅓)³⁻⁰ = 1/27
P(1) = ₃C₁ (⅔)¹ (⅓)³⁻¹ = 2/9
So the probability that it rains on at most one day is:
P(at most 1) = 1/27 + 2/9
P(at most 1) = 7/27
P(at most 1) ≈ 0.259
Answer:
50/100
Step-by-step explanation:
it is a half becaus 50 is half of 100 1 is hal of 2
Answer:
99
Step-by-step explanation:
0.13+0.05+0.21+0.19+0.3=0.88
1- 0.88= 0.12 meaning the chance of rolling a 3 is a 0.12 chance.
0.12+0.21 = the probability of rolling a 3 or 4= 0.33
0.33x300= the probability of the total times the dice will land on 3/4 when rolled 300 times= 99
Answer:
30 is the perimeter i think 2 x 5 = 10 + 2 x 4.5 = 10 x 2 = 20 so 20 + 10 = 30
I think the area is 45, 5 x 4.5 = 22.5 and 2 x 22.5 = 45
