A single card is drawn from a 52 standard deck. Find the conditional probability that the card is a heart given that it's a jack
MakcuM [25]
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>

I need help asap !! i’ll make brainliest !! 25 points
valentinak56 [21]

Answer:

I believe it is the second answer;

F(x)= (1/2)(2)^x

Step-by-step explanation:

1. the initial value is 0.5, so the first number will have to be 1/2, and it is increasing so the value of <em>b</em> must be above 1.

2. Through process of elimination, you can determine that the second equation matches the graph.

I hoped this helped! Please comment if you have any questions :)
