<h3>Answer: 0.47178 Step-by-step explanation:
Find the probability for each p(X=x) up to 5 using the equation: (x-1)C(r-1)*p^r * q^x-r,
where x is number of days, p = .3 (prob of rain). q=.7 (prob of not rain), and r=2 (second day of rain). also C means choose.
So p(X=1) = 0
p(X=2) = 1C1 * .3^2 * .7^0 = .09
P(X=3) = 2C1 * .3^2 * .7^1 = .126
P(X=4) = 3C1 * .3^2 * .7^2 = .1323
P(X=5) = 4C1 * .3^2 * .7^3 = .12348
Then add all of them up
0+.09+.126+.1323+.12348 = .47178</h3>
Answer:
Step-by-step explanation:
We will solve the given expressions and find the answer in decimals.
1). 
= 
= 5.4 - 2.8
= 2.6
2). 
= -3.3 + 0.35
= -2.95
3). 
= -3.125
4). (-4.5) × (-2.3) = 10.35
Solution of the expressions in the increasing order will be,
-3.125 < -2.95 < 2.6 < 10.35
You draw a vertical line on the point (3,0) and a vertical like looks like———>>> | , then whatever shape or point it gives you, you reflect off of that line like if it was a mirror
You would need the table to figure this problem out, but here we go!
15000×.018= 270
15000×.020= 300
15000×.023= 345
270+300+345= $915
