Answer:
Step-by-step explanation:
Chances of no head = ⁵C₀(1/2)⁰(1/2)⁵ = 1/32 => (1/32)*3200 = 100
Chances of 1 Head = ⁵C₁(1/2)¹(1/2)⁴ = 5/32 => (5/32)*3200 = 500
Chances of 2 Head = ⁵C₂(1/2)²(1/2)³ = 10/32 => (5/32)*3200 = 1000
Chances of 3 Head = ⁵C₃(1/2)³(1/2)² = 10/32 => (5/32)*3200 = 1000
Chances of 4 Head = ⁵C₄(1/2)⁴(1/2)¹ = 5/32 => (5/32)*3200 = 500
Chances of 5 head = ⁵C₅(1/2)⁵(1/2)⁰ = 1/32 => (1/32)*3200 = 100
