The probability that he got at least 2 questions correct is 0.756.

Probability is simply how probably something is to appear. every time we're uncertain approximately the final results of an occasion, we can communicate approximately the possibilities of positive outcomes and how in all likelihood they may be. The analysis of occasions ruled through chance is called data.

Basic Probability Rules

  • For any event A, 0 ≤ P(A) ≤ 1
  • The sum of the probabilities of all possible outcomes is 1
  • The Complement Rule
  • Probabilities Involving Multiple Events.
  • Addition Rule for Disjoint Events

The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many students are boys?
cricket20 [7]

Answer:

15 boys and 20 girls

Step-by-step explanation:

1. Since we cant simplify 3:4 we will leave it just like that.

2. 3x+4x=35

3. We add them both to give us 7x=35

4. We divide by 7 to get x by itself which results in 35/7=5.

x=5

5. Now we found x we can create 2 seperate soulutions:

3(5)=

and 4(5)=

Therefore there are 15 boys and 20 girls in the class. This makes sense because 15/20 reduced is 3 over 4.

pav-90 [236]
<span>= 49567/1000

</span>rite the decimal number as a fraction
(over 1)
49.567 = 49.567 / 1

Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's

Numerator (N)
N = 49.567 × 10 × 10 × 10 = 49567
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000

N / D = 49567 / 1000

Simplifying our fraction
