Answer:

B) 15/(9+(-9))

Step-by-step explanation:

Be careful of the parentheses because if you just write out 15/9+(-9),

it's technically, saying that 15/9+(-9)=5/3+(-9)=5/3-9, and that's different from what you want to express, mathematically.

A jar contains 12 caramels, 7 mints and 16 dark chocolates. What is the probability of selecting a mint? What is the probability

jarptica [38.1K]

Answer:

23/35

Step-by-step explanation:

Probability ratio will be expresses with denominators of 12+7+16=35

Probability of selecting carmel is 12/35

Probability of selecting mints is 7/35=1/5

Probability of selecting chocolates is 16/35

Probability of not selecting a carmel will be given by 1-probability of selecting a carmel since maximum probability is always 1 or 100%

Probability of not selecting a camel will be 1-12/35=35/35-12/35=23/35

Alternatively, the probability of not selecting a carmel is equivalent to the sum of probability of either selecting a dark chocolate or mint which will be 7/35+16/35=23/35

The answers are the same, 23/35
