An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water what is the probability of gett
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} .

What is the difference of the polynomials?<br><br>(8r6s3 – 9r5s4 + 3r4s5) – (2r4s5 – 5r3s6 – 4r5s4)
nignag [31]
(Distribute the minus sign of the subtrahend in each term.)
= 8r⁶s³ – 9r⁵s⁴ + 3r⁴s⁵ – 2r⁴s⁵ + 5r³s⁶ + 4r⁵s⁴
(Add or subtract like terms.)
= 8r⁶s³ – 5r⁵s⁴ + r⁴s⁵ + 5r³s⁶
(If you want to factor out, then...)
= r³s³ (8r³ – 5r²s + rs² + 5s³)
