6 is rolled. Find the probability of tossing a
head and then rolling a number greater than 4.
The probability of tossing a head and then rolling a number greater than 4 is 1/6. The probability says the number of possible outcomes from the total outcomes of an event.
The probability is defined as the ratio of the count of the favorable outcomes to the total count of the outcomes of the sample.
P(A) = n(A)/n(S) where A is n event, n(S) is the total count of the sample, and n(A) is the count of favorable outcomes.
The given events are tossing a coin and rolling a dice.
The favorable outcomes for these events are given as tossing a head and rolling a number greater than 4.
Calculating the probability of tossing a coin:
The total outcomes of the event are 2 (head and tail)
The favorable outcome = 1 (only head)
So, the probability of tossing a head = 1/2
Calculating the probability of rolling a dice:
The total outcomes of the event are 6 ( a dice has 6 faces with a number on each face (1 to 6))
So, there are only two numbers that are greater than 4 (5, 6)
The favorable outcomes = 2
So, the probability of rolling a numbergreater than 4 = 2/6 =1/3
Calculating the probability of two events at the same time:
To get this probability- multiply both the probabilities.
⇒ 1/2 × 1/3 =1/6
Therefore, the required probability is 1/6.

It is A. 2x+5
Bill is twice as old as Sharon, making it 2x.
Jason is 5 years older than Bill, making it 2x+5
(It can also be B. because 2x+5 and x2+5 are the same thing)
Answer:
A is the correct answer m8
Answer:
Not sure how the question goes.
Step-by-step explanation:
2Y - 4X
2(9) - 4(2) = 18 - 8 = 10
Or
Y^2 - X^4
(9)^2 - (2)^4 = 81 - 16 = 65
y2-x4
to solve this u need to place the variables for the given value
y= 9
x=2
(9)2-(2)4
9 times 2 is 18
2 times 4 is 8
18-8=10
or if it is
y^2-x^4
9^2- (2)^4
9^2=81
2^4=16
81-16 = 65
