Answer:
m=15
Step-by-step explanation:
m/9 + 2/3
x 3 7/3 x 3 = 21/9
m/9 + 6/9 = 21/9
21-6=15
15/9 + 6/9 = 21/9 = 7/3
Answer:
what's the math problem
Step-by-step explanation:
You can use the formula for conditional probability as Puzzling did. However in this problem it is easier just to restrict yourself and enumerate the cases that are left.
<span>There are 4 jacks. One of them is a heart. So the probability is 1/4. </span>
<span>If you want to look at what the formula for conditional probability does, it adjusts your probability by restricting the "universe". </span>
<span>P(heart and jack)/P(jack) </span>
<span>= (1/52)/(4/52) = 1/4</span>
