First you divide them all by 7 to see which are greater than 19
28/7=4
84/7=12
35/7=5
105/7=15
even if you add 1 to them they all are still less than 19
so select them all
hope this helps! :)
Pretty sure you gotta add 8x to 2x
Answer:
4/7
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given
Total outcome = 2blue ties+1red tie+2blue coats+2orange coats
Total outcome = 7
If he wears a blue tie, then the expected outcome will be 2.
Probability that he wears blue tie = 2/7
If he wears a blue coat, then the expected outcome will be 2.
Probability that he wears blue coat = 2/7.
The probability that he wears either a blue tie or a blue coat will be 2/7+2/7 = 4/7
Simplify the following:
(-6 (-8)×2×3 x x x x)/(3×4)
(8 x×2 x (-6) x×3 x (-1))/(3×4) = (8 x^4×2 (-6)×3 (-1))/(3×4):
(-6 (-8)×2×3 x^4)/(3×4)
8×2 = 16:
(-6 (-3)16 x^4)/(3×4)
16 (-6) = -96:
(-3-96 x^4)/(3×4)
-96 (-3) = 288:
(288 x^4)/(3×4)
3×4 = 12:
(288 x^4)/12
