Question

Summer is having a pool party at her house In the ice chest me are of lemonade and 13 bottles of water If she randomly grabs aborted from ’ w hat 15 the probability it is either a soda or lemonade

Answer 1

Probability =

(number of ways it can come out the way you want it to)
divided by
(total number of ways it can come out).

Total number of ways it can come out =

number of bottles in the cooler

= (10 + 15 + 13) = 38 .

Number of ways it can come out the way you want it to =

(soda + lemonade)

= (10 + 15) = 25 .

Probability of coming out the way you want it to =

25 / 38 = about 65.8 % .
