Answer:
0.218
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome of event/ Total outcome
If a bag contains 3 red marbles, 7 blue marbles and 5 green marbles, the total number of marbles in the bag will be the total outcome i.e 3+7+5 = 15
If two blue marbles are drawn, the expected outcome in both cases is 7 since there are 7 blue marbles in the bag.
Probability of drawing the first blue marble = 7/15
Probability of drawing the second blue marble = 7/15
Probability that both marbles drawn will be blue = 7/15*7/15
= 49/225
= 0.218 (to nearest 1000th)
Answer:
rise 4, run -2. the gradiant is 2
Step-by-step explanation:
(X1,Y1)___(X2,Y2)
| | | |
(-2,2)_____(0,6)
X1-X2, Y1-Y2.
-2-0= -2= (-2,_)
2-6= 4= (_,4)
(-2,4)
