Answer:
0.99
Step-by-step explanation:
Given,
Pink gumballs = 3,
Red gumballs = 4,
Green gumballs = 2,
So, total gumballs = 3 + 4 + 2 = 9,
Thus, total ways of selecting 5 gumball = 




Also, the total ways of selecting no red gumballs = 
= 1 × 1
= 1
So, the probability of no red gumballs in 5 drawn

Hence, the probability that a red gumball is drawn if there are 5 drawings
= 1 - probability of no red gumballs


≈ 0.99

Answer: 280 miles I think
Step-by-step explanation:
At first, he drives 110. Then hes at the 180 mile mark. And at the end he is at 280. 110 + 70 + 100. I’m very sorry if I’m wrong.
You can immediately read off the y-intercept; it is (0, -1).
To find the slope:
-3 - 0
m = ---------- = -1/3
