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>
Answer:
There are multiple ways to do so:
You can divide the number by 100 to convert it to a decimal
You could take your percentage and add a decimal two places to the left.
Examples of both:
For division its as simple as 75 divided by 100 = 0.75
If we are going to use the decimal method, lets say we have 45%, so we can do this:
45% =45.00
Move the decimal two places to the left.
0.45
3×2y-(1/3×3)=5×3
6y-1=15
6y-1+1=15+1
6y=16
y=8/3
Y cannot be 8
4,408,730 = 4,000,000 + 400,000 + <span>8,000 + 700 + 30 </span>
Answer:
it's 270! the formula for triangles is base times height divided by 2, the measurement on the side means nothing in context of finding area
