Pls answer quickly

use the following formula for calculating binomial probabilities to answer the question. (in picture)

what is the probability of getting exactly 5 “heads” in 10 coin flips?

a) 1/32
b) 63/256
c) 1/2
d) 193/256

Your question is related to the binomial probability

Although there is no picture, I will answer your question that is:

Find the probability of getting exactly 5 “heads” in 10 coin flips
Probability of getting a head = 1/5 and also 1/2 for getting a tail.
P(H) =1/2 and P(T) =1/2
Total # of flips =10;  Total # Heads requested = 5

¹⁰C₅ = (PH)⁵.P(T)¹⁰⁻⁵

¹⁰C₅ = (1/2)⁵.P(1/2)⁵ = 63/256  (answer B)

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000
