Solution :
Let x be student will be left handed
P = 0.09
Using the normal approximation to binomial distribution,
a). n = 108,
μ = np = 9.72
= 2.9741
Required probability,
P(x=8) = P(7.5 < x < 8.5)
Using z table,
= P(z<-0.41)-P(z<-0.75)
= 0.3409-0.2266
= 0.1143
b). P(x=12) = P(11.5 < x < 12.5)
Using z table,
= P(z< 0.94)-P(z< 0.60)
= 0.8294 - 0.7257
= 0.1006
Answer:
24 times
Step-by-step explanation:
Given : A small bottle of vanilla extract has 16 ounces in it.
To Find : if each batch of cookies baked requires 2/3 of an ounce of vanilla how many times can the bakery use the bottle before it is empty?
Solution :
No. of batch of cookies requires 2/3 ounce of vanilla = 1
No, of batch of cookies requires 1 ounce of vanilla =
No. of batches require 16 ounces of vanilla =
= 24
Thus, bakery can use 24 times the bottle before it is empty.
