Answer:
5/222
Step-by-step explanation:
you need to add all the cards together first
13 + 10 + 8 + 6 = 37
then you take out 1 card to find the first probability of the blue card (there are 6 blue cards out of 37)
so 6/37
that will be your first probability
then for the 2nd probability, you will have 1 less card grom the deck making it only 36 cards (after taking out the first one, there will be only 5 blue cards left)
making it 5/36
that will be the 2nd probability
then you multiply both these probabilities to find the answer
6/37 × 5/36 = 5/222
Hence the value of a is: 3b/2
Answer:
x + y = 0
Step-by-step explanation:
Slope 1
b = -2 - (-1)(2)
b = -2 +2
b = 0
y = -x
Answer:
Sample space: {1, 2, 3, 4, 5, 6}
Simple event
Step-by-step explanation:
Sample space is a list of all the possible outcomes.
This is a simple event because you are only doing one event, such as rolling a die.
A compound event would be multiple simple events, such as flipping a coin <em>and </em>choosing a marble from a bag.
Answer:
(x,y) (1,-1)
Step-by-step explanation:
y=3-4x
-x+2y=-3
x+2(3-4x)=-3
x=1
y=3-4*1
y=-1
