It is given that there are 4 cards with numbers 2, 5, 6, and 8.
1) It is required to list all the numbers available when two cards are drawn one after the other and the second card is placed at the right of the first card drawn.
To do this, find the sample space of the draw which are:
Hence, the required numbers.
2) Recall that probability is the ratio:
From the numbers listed, notice that the total number of possible outcomes is 12.
Since event A is "obtained number is even", notice that the number of even numbers in the listed numbers is 9 (26,28,52,56,58,62,68,82,86).
Hence, the number of favorable outcomes is 9.
Substituting into the probability ratio gives the required probability:
Check the number of numbers that are a multiple of 5, notice that they are 3 (25,65,85).
Hence, the required probability of event B is:
The number of multiple of 3 in the listed numbers is 0 since there is no number that is a multiple of 3.
Hence, the required probability of event C is:
Answers:
1) {25,26,28,52,56,58,62,65,68,82,85,86}
2) P(A) = 3/4
P(B) = 1/4
P(C)= 0
Answer:
(5, 0) and (4, 0)
Step-by-step explanation:
According to the graph shown, the parabola passes trough the points (4,0) and (5,0). Therefore, they are the x-intercepts of the parabola.
Answer:
y = x + 2
Step-by-step explanation:
As the equation of a line is in the form y = mx + c:
Step 1 - Calculate the y intercept
This can be done by looking at the y coordinate where x = 0:
y = mx + c
In the picture, the y intercept is 2 so:
y = mx + 2
Step 2 - Calculate the slope
This can be calculated by:
Get two sets of coordinates:
(0, 2) and (2, 4)
Calculate the changes by subtracting from one another:
So the gradient is 1, meaning the equation of the line is:
