x. 250
_____ _____
7.30 100
cross multiply
100x = 1825
divide the 100
x = 18.25
0.33 -0.6 -0.666666 that's how they would go
Answer: d) 0.238
Step-by-step explanation:
We would assume binomial distribution for the number of men sampled. The formula for binomial distribution is expressed as
P(x =r) = nCr × q^(n - r) × p^r
Where
p represents the probability of success.
q represents the probability of failure.
n represents the number of samples.
From the information given,
n = 10
p = 65% = 65/100 = 0.65
q = 1 - p = 1 - 0.65 = 0.35
The probability that exactly six of them will consider themselves knowledgeable fans is expressed as P(x = 6). It becomes
P(x =6) = 10C6 × 0.35^(10 - 6) × 0.65^6
P(x =6) = 10C6 × 0.35^4 × 0.65^6
P(x =6) = 0.238
P(BB)=(4/12)(3/11)=12/132=1/11
P(RG)=(3/12)(5/11)=15/132=5/44
