there are 6 faces of dice :1,2,3,4,5,6
total no. of faces(N)= 6
to make four it should= (1+2) (2+2) (3+1)
total no of dice(n) = 2
formula=
probability= 3/36
=1/12
No as it doesn’t go vertically through 1/3 on x axis
Answer:
- B. The probability that the student received a grade better than C is 0.45
Step-by-step explanation:
<u>Total number of students:</u>
- 15 + 30 + 35 + 16 + 4 = 100
<h3>Statements</h3>
A.
- p(<D) = 4/100 = 0.04
- 0.04 ≠ 0.2
- Incorrect
B.
- p(>C) = (30 + 15)/100 = 45/100 = 0.45
- 0.45 = 0.45
- Correct
C.
- p(not A or B) = (100 - 15 - 30)/100 = 55/100 = 0.55
- 0.55 ≠ 0.45
- Incorrect
D.
- p(B or C) = (30 + 35)/100 = 65/100 = 0.65
- 0.65 ≠ 0.35
- Incorrect
Answer:
A. Yes
B. Yes
C. No
Step-by-step explanation:
We can substitute each value in to the equation and see if the sides match up. Let's start with a.
So, n = 2 works for equation a. Let's try B.
So, m = 
works for B. Now let's try C.
So y = 30 doesn't work for C.
Hope this helped!
