Suppose a quiz has 12 multiple choice questions. Each question has 4 answer choices. If a student takes the quiz and randomly gu

Gnoma [55]

The probability that the student gets between 1 and 6, exclusive, questions correct will be 0.7872...

Explanation

If the probability of success is $p$ , then the probability of $r$ successes in $n$ trials will be......

$P = ^nC_{r}*(p)^r (1-p)^n^-^r$

Here, the quiz has total 12 questions and each question has 4 answer choices. So, $n=12$ and $p=\frac{1}{4}= 0.25$

The student gets between 1 and 6, exclusive, questions correct. It means there can be 2 or 3 or 4 or 5 questions as correct. So....

The probability of 2 or 3 or 4 or 5 questions correct will be:

$=^1^2C_{2}*(0.25)^2(1-0.25)^1^0 + ^1^2C_{3}*(0.25)^3(1-0.25)^9 +^1^2C_{4}*(0.25)^4(1-0.25)^8+^1^2C_{5}*(0.25)^5(1-0.25)^7\\ \\ =0.2322...+0.2581...+0.1935...+0.1032... \\ \\ =0.7872...$

In a basket of fruit, 5/6 of the pieces of fruit are apples. There are 20 apples in the display. The equation 5/6f= 20 can be us

labwork [276]

Answer:

There are 24 pieces of fruit in the basket.

Step-by-step explanation:

There are 24 pieces of fruit in the basket because to find how many there are you would do $\\ \frac{6}{5\\}\\ \\$ · $\frac{5}{6}$ f = 20 · 6/5 times 5/6 cancels out, and 20 time 6/5 is 24. 20/24 can also simplify to 5/6.

Hope this helps!
