Step-by-step explanation:
Given
3 - 2x² + 15x² - 10
Factor the first/second and third/fourth terms )
= x²(3x² - 2) + 5(3x² - 2) ← factor out (3x² - 2) from each term
= (3x² - 2)(x² + 5)

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
