A and B are two events.

maria [59]

Answer:

0.8

Step-by-step explanation:

We can solve P(A or B) by using the following:

$P(AorB)=P(A)+P(B)-P(AandB)$

Since we know P(A) = 0.6, P(B) = 0.3 and P(A and B) = 0.1 we obtain:

$P(AorB)=0.6+0.3-0.1=0.8$

A pair of coins is tossed. What is the probability of no tails? <br> 0 <br> 1/2 <br> 1/4

lesya [120]

0 cannot be the answer. It makes no sense because you can get a probability of getting tails when flipping a coin.

The answer would be 1/2. You have '2' choices (heads or tails) and 1 out of those 2 times would you possibly get tails.

kondaur [170]

Answer: 0.8031

Step-by-step explanation:

Binomial distribution:

For a binomial variable x,

The probability of getting success in x trials = $P(X=x)=^nC_xp^x(1-p)^{n-x}$

, where n = Total trials .

p= Probability of getting success in each trial.

For the given situation , we take x as the number of damaged apple .

Given : The proportion of damaged apples : p=0.15

n= 10

Then, the probability that his sample will contain at least one damaged apple. :-

$P(x\geq1)=1-P(x$

Hence, the required probability = 0.8031

All points from which of the following patterns would be contained on the given graph?

NeX [460]

Answer:

Step-by-step explanation:

Slope of the line is -3. y-intercept is 3.

So, the rule for this line is y= - 3x+3.

The pattern of y-values that can fit is B.

y=0, x= 1

y=-3, x=2

y=-6, x=3

and so on.
