Required
Probability of selecting a yellow then orange rock
From the question, we understand that the probability is that of without replacement.
Since the yellow, is first picked.
We need to determine the probability of picking a yellow rock, first.



The rock has reduced by 1;
Next is to determine the probability of picking an orange rock



The required probability is calculated as thus:




Answer:

Answer:
l=5+2w
Step-by-step explanation:
Since the length is twice the width plus 5, the equation would look like :
l=5+2w
So its
1/3 divided by 6/1
we get the reciprocal
1/3*1/6
so thats 1/18 for each sports team
