0.41 x 7 = 2.87
Answer:
<h2>
12</h2>
Solution,
Summation FX= 5+10+6+12+X
=33+x
N(total no.of items)=5
Now,
Mean= summation FX/N
or 9=33+X/5
or 9*5=33+X ( cross multiplication)
or 45=33+X
or -x=33-45
or -x=-12
X=12
Hope this helps...
Good luck on your assignment..
Answer:
0.7223
Step-by-step explanation:
Given:
Probability of hitting, p = 0.226
Number of times player bats, n = 44
Now,
P (getting a least one hit) = 1 - P ( no hits )
also,
P( not hitting a hit in game )= qⁿ
where,
q = 1 - p
thus,
q = 1 - 0.226 = 0.774
Therefore,
P ( not hitting a hit in game ) = 0.774⁵ = 0.2777
Hence,
P ( getting a least one hit ) = 1 - P ( no hits )
or
P ( getting a least one hit ) = 1 - 0.2777
or
P ( getting a least one hit ) = 0.7223
