Answer:


P(S&G) =0.7941

Explanation:

From the question we are told that:

Sample size
n=16+18=>34

N0 of Large
L=16

N0 of Small
S=18

N0 large Green
L_g=9

N0 of small White
S_w=3

Therefore

Number of green marbles
N0(G)=9+(18-3)

Number of green marbles
N0(G)=24

Generally the Number of both small and green Marble is


N0 of (S&G)= 18 - 3 = 15

Generally the probability that it is small or green P(S&G) is mathematically given by


P(S&G) = ((18 + 24 - 15))/((18 + 16))


P(S&G) =0.7941
