Question

A jar has one blue and nine green marbles in it. What is the probability of drawing a green marble?​

Answer 1

Answer:

Probability = 9/10

Step-by-step explanation:

Let's name blue marble as b and green marble as g.

Sample Space = {b, g, g, g, g, g, g, g, g, g}

Number of favourable outcomes = 9

Probability

= Number of favourable outcomes / Total number of outcomes

= 9/10

Hence, probability of drawing a green marble is 9/10.

Answer 2

Answer:

blue marble = 14

green marble =33

Step-by-step explanation:

let the number of blue marble is x then

number of green marble equals to 2 X + 5

total Marbal =X + 2 X + 5 =32 + 5

p(blue) =2\7

x\2x+7= 2\7 (p(blue)=x\2x+7)

7x+6x+14 =14

number of blue marbles =14

number of green marbkes =33
