If you multiply 24 and 3 and then divide your answer will be 9
How to set up you problem.
w - 7 > - 4 To solve the inequality, you need to get the variable (w) by itself, to do so, you add 7 on both sides of the inequality
w - 7 + 7 > -4 + 7
w > 3 [w is a number greater than 3]
(If you are using an open circle and closed circle, otherwise you can skip)
When the sign is < or >, you have an open circle "o"
When the sign is ≤ or ≥ (less/greater than or equal to), you have a closed circle
Make an open circle on the number 3, then make an arrow pointing to the right because w is greater than 3.
If you don't have to do the open/closed circle, just make a dot on the number 3 and make an arrow pointing/going to the right
Answer:
5/21.
Step-by-step explanation:
Total number of balls = 7.
Prob(Blue on first pick) = 3/7
Prob(Blue on second pick) = 2/6 = 1/3
So Prob( 2 Blue's) = 3/7 * 1/3 = 3/21 = 1/7.
Prob(Red on first pick) = 2/7
Prob(Red on second pick) = 1/6
So Prob( 2 Red's) = 2/7 * 1/6 = 1/21.
Now the Probability of getting 2 white balls is the same as for the red balls
= 1/21.
Finally, the probability of 2 balls of the same colour
= 1/7 + 1/21 + 1/21
= 3/21 + 1/21 + 1/21
= 5/21.
