Answer:

$P(E\ or\ F) = 0.60$

Step-by-step explanation:

Given

$P(E) = 0.25$

$P(F) = 0.40$

$P(E\ and\ F) = 0.05$

Required

Determine P(E or F)

This is calculated using:

$P(E\ or\ F) = P(E) + P(F) - P(E\ and\ F)$

$P(E\ or\ F) = 0.25 + 0.40 - 0.05$

$P(E\ or\ F) = 0.60$

Find the product. (3n - 1)(7n-7)

slega [8]

Answer:

21n² - 28n + 7

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

3n(7n - 7) - 1(7n - 7) ← distribute both parenthesis

= 21n² - 21n - 7n + 7 ← collect like terms

= 21n² - 28n + 7

timurjin [86]

Answer:

Option B.

Step-by-step explanation:

Two events are said to be independent of each other, if the probability of one event ocurrin in not way affects the probability of the other event occurring.

The interception of two independent events P(A ∩ B) = P(A) × P(B), where:

P(A) = 0.70

P(B) = 0.20

P(A ∩ B) = P(A) × P(B) = 0.70x0.20 = 0.14

The two events are independent if the probability of buying Bread AND cheese equals: 0.14, which is Option B.
