So we basically need to find 35% of 20. An easy way to find percents is to multiply by the decimal form of said percent. So, .35 x 20 = 7.

Answer:

$\red{{7}^{15} }$

Step-by-step explanation:

We know that,

${x}^{a} \times {x}^{b} = {x}^{a + b} \\ ( {x}^{a} ) ^{b} = {x}^{ab}$

Accordingly,

$( {7}^{5} ) ^{3} \\ {7}^{5 \times 3} \\ {7}^{15}$

Suppose that 20° of boys opted for mathematics and 40% of girls opted for mathematics. What is the probability that a student op

ankoles [38]

Answer: 30%

Step-by-step explanation:

Let A be the probability of a student opting for mathematics - it consists of either boy opting for mathematics or girl opting for mathematics. As there is "or" we need to sum these probabilities.

$P(A) = P(B)* P(M|G) + P(G)*P(M|G)$

$P(A) = \frac{1}{2} * \frac{20}{100} + \frac{1}{2} * \frac{40}{100}$

$P(A) = 3/10 = 0.3$

=> 30%
