2.
probability= all possible outcome/total outcome
total marbles=5+3+8=16
orange marbles=3
Probability of picking orange without looking =3/16
3) total cards are 52
probability of picking 5 from any suits=5/52
4) EMBRYONIC
total letters are 9
picking R or E
we can randomly
E
M
B
R
Y
O
N
I
C
picking either R or E possibility is 1
so probability=1/9
