Abag has 2 green marbles, 3 red marbles, and 3 yellow marbles. what is the probabilty that you pick a yellow marble, do not replace it, and pick another yellow marble?
3/28
1/28
9/56
1/8

Probability of picking 2 yellow marbles WITHOUT REPLACEMENT

=

Step-by-step explanation:

Number of green marbles = 2

Number of red marbles = 3

Number of yellow marbles = 3

So, the total number of marbles  =  2 + 3 + 3 =  8 marbles

Let E : Event of picking a yellow marble from the bag

Now, Probability of an Event E =

⇒ Here,

After picking 1 yellow marble from the bag:

Total marbles left in bag = 8 -1 = 7

Total yellow marbles left in bag = 3 - 1 = 2

Now, the probability of picking the second yellow marble WITHOUT REPLACEMENT =

So, the Probability of picking 2 yellow marbles WITHOUT REPLACEMENT

=

what is the original number? you forgot to add it.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
