PLEASE HELP ILL MARK BRAINLYIST

Angel is selling Girl Scout cookies. She has 5 boxes of Thin Mints, 7 boxes of Tagalongs, and 10 boxes of Smores. Mandy picks a box at random to buy. It is the Tagalongs, but she decides to return it and pick another box. What is the probability that Mandy will pick Thin Mints? (type as fraction)

Answer 1

Answer:

The probability is $\frac{5}{22}$

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.  

The size of the sample space is the total number of possible outcomes  

The event space is the number of outcomes in the event you are interested in.  

so  

Let

x------> size of the event space

y-----> size of the sample space  

so

$P=\frac{x}{y}$

In this problem we have

$x=5\ boxes\ of\ thin\ Mints$

$y=5+7+10=22\ total\ boxes$

substitute

$P=\frac{5}{22}$
