Because when you round 364,573 to the nearest thousand , you get 360,000 and when you round 64 , you get 60 and if you take away the zeros, the equation is basically 36÷6

The probability that a random student at Elmville College is a freshman is 0.3; a sophomore, 0.25; and a junior or senior, 0.45.
Andre45 [30]
Let L_1 denote the event that a student is a freshman, L_2 a sophomore, L_3 a junior, and L_4 a senior.

Let E denote the event that a student majors in engineering. By the law of total probability,

\mathbb P(E)=\mathbb P(E\cap L_1)+\mathbb P(E\cap L_2)+\mathbb P(E\cap L_3)+\mathbb P(E\cap L_4)

By the definition of conditional probability, we can expand each of these intersection probabilities to get

\mathbb P(E)=\mathbb P(E\mid L_1)\mathbb P(L_1)+\mathbb P(E\mid L_2)\mathbb P(L_2)+\mathbb P(E\mid L_3)\mathbb P(L_3)+\mathbb P(E\mid L_4)\mathbb P(L_4)

\mathbb P(E)=0.15\cdot0.3+0.2\cdot0.25+2(0.3\cdot0.45)=0.365

How to solve step by step
nasty-shy [4]
A/7 + 5/7 = 2/7

1/7a + 5/7 = 2/7

1/7a + 5/7 - 5/7 = 2/7 - 5/7
1/7a = -3/7

7*(1/7a) = 7*(-3/7)
a = -3

Alice tried to solve the equation. What was her mistake?
uysha [10]
She didn’t multiply -1/4 by 12 in order to get -1/4x + 3 = -1

which would change her answer, because then you have to subtract 3 from -1 and get -4. Then divide -1/4 & get 16. It changed to positive because of the division & multiplication rule with two negative numbers.


Hope this helps.
