Answer:
The probability that he has exactly 2 hits in his next 7 at-bats is 0.3115.
Step-by-step explanation:
We are given that a baseball player has a batting average of 0.25 and we have to find the probability that he has exactly 2 hits in his next 7 at-bats.
Let X = <u><em>Number of hits made by a baseball player</em></u>
The above situation can be represented through binomial distribution;

where, n = number of trials (samples) taken = 7 at-bats
r = number of success = exactly 2 hits
p = probability of success which in our question is batting average
of a baseball player, i.e; p = 0.25
SO, X ~ Binom(n = 7, p = 0.25)
Now, the probability that he has exactly 2 hits in his next 7 at-bats is given by = P(X = 2)
P(X = 2) =
=
= <u>0.3115</u>

Answer: 4×15= 60
Step-by-step explanation:
60 is 15 times as many as 4. This means that 15 is multiplied by 4 to get 60. This will be :
4×15= 60.
The other options such as 60÷15=4, 15+4= 60, 60÷4=15 and 60-15= 4 doesn't explain the question given. 60-15 is not 4 likewise 15+4 isn't 60. For the other options, the question isn't talking about division but multiplication.
