5/8 or .625 is the answer
The book has 100+44=144 pages.
She spent 2+1=3 hours on reading = 3*60=180 minutes
The "speed" will be 144/180 = 0.8 pages per minute

Answer: a) 0.0058
b) 0.0026
Step-by-step explanation:
Given : The probability of having clear sunny skies in Seattle in July : p= 0.40
The number of days spent in Seattle in July: n= 18
a) Using, Binomial probability formula : 
The probability of having clear sunny skies on at least 13 of those days:-




b) On converting binomial to normal distribution, we have

Let x be the number of days having clear sunny skies in Seattle in July.
Then, using
we have

P-value = 

Answer:
x = -6 ; y = -1
Step-by-step explanation:
2 x - y = - 11 .........equ No 1
- 2 x - y = 13 .........equ No 2
Adding equ No. 1 and equ No. 2
- 2 y = 2
∴ y = - 1
substituting y = -1 in equ no 1
2 x - ( -1) = -11
2 x + 1 = - 11
2 x = -11 - 1
2 x = -12
∴ x = -6
x = -6 ; y = -1
