A fraction with the numerator (the top number) being larger then the bottom is an improper fraction. 4/2
A fraction with the denominator (bottom fraction) being heavier is a proper fraction. 2/4
A normal fraction with a whole number next to it is a mixed fraction. 2 4/5
22-12=35x
10=35x
10/35=x
2/7=x
your answer is
x= 2/7
This is a case of joint probability: you want to know what the odds are of this event AND that event occurring. For a joint probability, the formula is usually given as:
P(A and B)=P(A)*P(B)
where P(A) is the probability of event A happening, P(B) is the probability of event B happening, and P(A and B) is the probability of both happening.
For this problem, let's say that event A is the probability that the spinner stops at the green color. Since the spinner has 3 colors and they have equal area (sector) occupied in the circle, each color has the same chance, 1/3 chance of being picked. Thus, there's a 1/3 chance of the spinner stopping at the green color so P(A)=1/3.
Event B is the probability of Jordan picking up the yellow card. There are six possible colors to pick and since Jordan picked up the card without peeking, each color has an equal chance to be picked. Thus, there's a 1/6 chance that the yellow card will be selected so P(B)=1/6.
Using the formula, we can then calculate P(A and B), the probability that the spinner stops at green and a yellow card is selected:
P(A and B)=P(A)*P(B)=1/3*1/6=1/18
Answer:
The number of the students is 20.
Step-by-step explanation:
Total number of students in the speech contest = 90
Number of students that gave their speeches yesterday =
of 90
=
x 90
= 60
Number of remaining students who have not given their speeches after the first day = 90 - 60
= 30
Number of students that gave their speeches today =
of 30
=
x 30
= 10
Number of students that have not given their speeches = 30 - 10
= 20
Thus, 20 students have not given their speeches.
