a.0.3694b.0.5266c.0.4734d.0.2305

Short Answer

Expert verified

b.0.5266

Step by step solution

01

Given information

Given that
San Jose sharks will win any given game is0.3694
P=0.3694(1−P)=1−0.3694=0.6306
The upcoming month schedule contains 12 games .(n)=12

02

Explanation

We know that
Binomial Probability

Probability that San Jose Sharks will win 5 games in the upcoming month. =P(X<5)
Here,
n=12,x=0,P=0.3694
Then binomial probability

P(X)=n!X!(n−X)!⋅pX⋅(1−p)n−X

P(0)=12!0!(12−0)!⋅0.36940⋅(1−0.3694)12−0

P(0)=0.0039540995304692

To calculate any remaining probabilities, we need to either use the binomial probability distribution function on a calculator or the binomial probability formula. We'll add these remaining probabilities to P(0) for our final answer.

P(0)+P(1)+P(2)+P(3)+P(4)0.0039540995304692+0.027795325719416+0.089552431436945+0.17486345370973+0.23047535609078=0.52664066648735

The probability to win at least five games in that upcoming month is0.5266

He attends exactly five events 35%of the time, four events 25%of the time, three events 20%of the time, two events 10%of the time, one event 5%of the time, and no events 5% of the time.
