Suppose a bag of marbles has 4 green, 2 red, 5 yellow, 1 brown, and 7 blue marbles. what is the probability of picking a green marble?

The bag of marbles has 4 green, 2 red, 5 yellow, 1 brown, and 7 blue marbles.

Total number of marble=4+2+5+1+7=19

The probability P(E) is defined as

where n(E) is the total number of favourable events.

and n(s) is the total number of events

Hence for the given data we can write

Because total number of green marbles = n(E)=4

Total number of Marbles =n(S)=19

Hence P(E)=4/19

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
