The following statement is false

  • Addition rule: The probability of event A or event B occurring is equal to the probability of occurrence of A  plus the probability of occurrence of B  minus the probability of both occurring.

  • If events A and B are mutually exclusive, then the probability of event A or B occurring is simply the sum of the probabilities.  

  • If A and B are two events in a probability experiment, then the probability of either event occurring is: P(A or B) = P(A) + P(B) −P(A and B)

  • Example: There are 12 face-up cards in a game, so P(head) = 12/52. There are 13 spades in a game, so P(flags) = 13/52.

The correct statement is that the probability of event a or event b occurring is p(a or b) = p(a) p(b) - p(a and b).

Hence the statement is False.

Answer:

The following statement is false

Step-by-step explanation:

The following statement that The probability that event a or event b will occur is p(a or b) = p(a) p(b) - p (a or b) is false

The correct statement is The probability that event a or event b will occur is p(a or b) = p(a) p(b) - p (a and b)

Addition Rule: The probability that event A or event B happens is equal to the probability that A happens plus the probability that B happens minus the probability that both happen. If events A and B are mutually exclusive, then the probability that event A or B happens is simply the sum of the probabilities.

PLEASE HELP. Susan needs to buy plastic forks. Brand A has a box of 25 forks for $2.12. Brand B has a box of 72 forks for $5.09.
torisob [31]

To find the price per unit, divide the total price by the number of units.

2.12/25=0.08

5.09/72=0.07

Brand B is the better buy. It is cheaper per unit.

Answer:

2

Step-by-step explanation:

Given:

-2(1-4x)=3x+8

Let's distribute the parenthesis

-2+8x=3x+8

Let's subtract -3x from both sides

-2+5x=8

Let's add 2 to both sides

5x=10

Now, let's divide both sides by 5 to get x alone

x=2

Hope this is helpful

Suppose that you buy a bond with face value $4000 that was originally issued 18 months ago. The maturity date is 4 years from th
Marta_Voda [28]

Answer:

amount of interest is  $267

total profit is $173

profit % is 4.86 %

Step-by-step explanation:

Given data

face value = $4000

time period  = 18 months = 1.5 years

maturity 4 years

interest = 3%

principal  = $3560

to find out

amount of interest, profit , percent of your investment is the profit made

solution

we know time period is lapsed for 1.5 years i.e now interest for time 2.5 year will be calculate

first we calculate the interest i.e

interest = ( principal × rate × time ) /100 ...........1

put all value principal, rate and time in equation 1 we get interest i.e.

interest = ( 3560 × 3 × 2.5 ) /100

interest = $267

so now total amount with interest will be

principal + interest

amount = $3560+$267

amount = $3827

so total benefit we get i.e. face value - total amount

total benefit = face value - total amount

total benefit = $4000 - $3827

total benefit = $173

so total profit is $173

and profit % = ( profit / principal ) × 100

profit % = ( 173 / 3560 ) × 100

profit %  = 4.859 %

so total profit % is 4.86 %
