Anna [14]

Answer: \dfrac{3}{8}

Step-by-step explanation:

Given: An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water.

Total drinks= 10+15+15 = 40  (Total outcomes)

Number of drink that does not contain fruit juice = Number of bottles of water = 15  (Favorable outcomes)

The probability of getting a drink that does not contain fruit juice = \dfrac{Favorable\ outxcomes}{Total\ outcomes}

=\dfrac{15}{40}\\\\=\dfrac{3}{8}

So, the required probability = \dfrac{3}{8} .
