Answer:
Step-by-step explanation:
Given that
(3x) is raised to power 5
(3x)^5
Then,
Using indices
(AB)ⁿ = Aⁿ•Bⁿ
Then,
(3x)^5= 3^5•x^5
Then, 3^5 means=3×3×3×3×3=243
So,
(3x)^5= 243x^5
Oh god not again.....................
P(all 4 are male) = 1/2^4 = 1/16 ( assuming probability of 1 male = 1/2)
P( 3 are male) = 1/2^4*4 = 1/4
The rest will have at least 2 females
So probability of at least 2 females) = 1 - 1/16 - 1/4 = 1 - 5/16 = 11/16 answer
