In Jennifer's bag, there are 7 marbles. Out of 7 marbles, 4 of them are blue.
Hence, the probability that Jennifer picks one blue marble is 4/7. (Option 1).
Blank 1: 1
Blank 2: 3
Blank 3: -2
This is impossible in 1 roll
the probability is zero
A.) 1/3 - 3(2/7x) - (3)(4) No because - (3)(4) is -12
B.) 1/3 - 6/7x + 12 Yes
C.) -11 2/3 - 6/7x No because 37/3 is 12 1/3
D.) 12 1/3 - 6/7x Yes
E.) 1/3 - 6(1/7x - 2) = 1/3 - 6/7x + 12 Yes
F.) 1/3 + (-3)(2/7x) - (3)(4) No because - (3)(4) is -12
Your answer is B, D, and E
