1 answer:

4 0

We are given with a number of marbles in different colors. The sample space includes all the marbles inside the bag, hence tehere are 16 marbles. The probability of getting a red or blue marble is the sum of probability of getting a red marble alone and that of a blue marble alone. Hence the answer is (6+4)/16 equal to 5/8

Find the area of the composite figure.

vivado [14]

So in fig 1 :

L = 14m
W = 9m

Area = L × W
Area = 9 × 14
Area = 126 m²

In fig 2 :

L = 7m
W = 16 - 9 = 7m

Area= L × W
Area = 7 × 7
Area =49m²

TA = 126 + 49
TA = 175 m²
