<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>
1.08=x idk I think I. Hope this helped
Answer:
Option d.
Step-by-step explanation:
It is given that Aarav has 3,250 followers on social media. His number of followers is increasing at a rate of 3% per week.
Initial followers = 3,250
Rate =
The exponential growth function is
where, a is initial value, r is rate and w is time per week.
Substitute a=3,250 and r=0.03.
Therefore, the correct option is d.
