A bag contain 7 blue and 2green marble. if the marbel drawn is blue and not replaced in the bag ,what is the probility of drawing a blue marbel next?

3/4

Step-by-step explanation:

7 blue balls and 2 green balls

so if we take a blue ball and do not put it back into the bag it will become 6 blue balls.

Now we need to find what is the probability of getting a blue ball next .

So our formula will be

= No of Blue balls / Total number of balls(No. of green + No. of Blue balls)

= 6/ 8

3/4( when you simplify it)

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
