Need !
from a barrel of colored marbles, you randomly select 1 blue, 2 yellow, 7 red, 6 green, and 2 purple marbles. find the experimental probability of randomly selecting a marble that is not yellow.
a.)11/18
b.)7/9
c.)9/10
d.)8/9

Option D

The probability of randomly selecting a marble that is NOT yellow is

Solution:

Given that , From a barrel of colored marbles, you randomly select 1 blue, 2 yellow, 7 red, 6 green, and 2 purple marbles.

Total possible outcomes = 1 blue + 2 yellow + 7 red + 6 green + 2 purple marbles = 18 marbles

So, for the event of picking a non yellow marble, we have to avoid yellow marble

Number of favourable outcomes = 1 blue + 7 red + 6 green + 2 purple marbles = 16 marbles

So, the probability for not picking yellow marble is So option D is correct.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

i did it myself and i got 4.2 (b) hope its right
