Question

Answer question 1 & 2 asap please

Question 1 As shown in the Venn diagram below, P and Q are events in the sample space S. Indicate the event by shading the appropriate region(s). (If necessary, consult a list of formulas.) S P x 5 ? e

Answer 1

Question 1)

S P

We have indicated $\bar{Q}$ by gray color shade.

i.e. $\bar{Q}$ means a region that does not include Q

Question 2)

Here p=1% = 0.01

And sample size is 80

This is Binomial Distribution

Therefore X~ B(n=80, p=0.01)

Now

a) mean = np= 80*0.01 = 0.8

Thus mean = 0.8

b) Standard deviation is,

$\sigma=\sqrt{npq}$

$\sigma=\sqrt{80*0.01*0.99}$

$\sigma=\sqrt{0.792}$

$\sigma=0.8899$

Thus standard deviation is 0.8899
