Answer:
b⁴ + 16b³ + 28b² - 242b + 780
Step-by-step explanation:
(b+10) (b³+6b²-32b+78)
b⁴ + 6b³ + 10b³ - 32b² + 60b² + 78b - 320b + 780
= b⁴ + 16b³ + 28b² - 242b + 780
Answer:
Step-by-step explanation:
Given:
The two statements.
To find:
The probability of an impossible event.
The probability of a certain event.
Solution:
Formula for probability is:
For an impossible event, the possible favorable outcomes is 0. So,
For a certain event (sure event), the possible favorable outcomes is equal to total number of outcomes. So,
Therefore, an event that is impossible has probability 0 and an event that is certain has probability 1.
