29=0.29 0.29*188=54.52 i think this is right but i may be wrong
No that is correct. it is 90 people. because 60% of 150 people is 90 people not 80
Answer:
P(x=25)=P(z=2)=0.9972 or 99.72%
Step-by-step explanation:
Mean = 18 pounds
Standard Deviation = 3.5 pounds
x= 25
We need to find P(x=25)
First, we need to find z-score using formula: 
Finding z-score when x=25

So, we need to find P(z=2)=P(x=25)
Looking at z-score table we can find P(z=2)
P(z=2)=0.9972 or 99.72%
So, P(z=2)=0.9972 or 99.72%
0.004 is the probability of getting exactly 0 tails :)
