Please mark me as the Brainliest

Step-by-step explanation:

P(A) = n(A) / n(s)

n(s) = n(A) / P(A) = 39 / (2/3) = (39/2) (1/3) = 13/2 or 6.5

n(s) = (13/2) or 6.5

Answer 2

Step-by-step explanation:

• P(A)= n(A)
• n(S)
• 2/3=39/n(s)
• by cross multiplication
• n(s)×2=39×3
• n(s)×2= 117
• n(s) =117/2
• n(s)= 58.5

n(S) =58.5
