D. P(A x B)

To work out the success of both events you have to multiply them together. I'd seriously reccomend learning this rule as it's very important later on in mathematics as it's basically the foundation of all probability statistics.

Answer:  The correct option is (B) P(A) • P(B).

Step-by-step explanation:  Given that the probability for success of an event is P(A) and the probability of success of a second event is P(B).

We are to find the probability of both events occurring, in that order.

We know that

if two events are independent of each other, then the probability of the intersection of the two events is given by the product of the probabilities of the events.

Here, the event that both events occur is given by (A ∩ B).

And, so the probability of both events occurring, in that order will be

P(A\cap B)=P(A).P(B).

Thus, the required probability is P(A) • P(B).

Option (B) is CORRECT.

Imagine the graph for the relation 4x-5y+20 = 0.<br> What would be its slope?
muminat
4x - 5y + 20 = 0
<u>             - 20  - 20</u>
        4x - 5y = -20
 4x - 4x - 5y = -20 - 4x
              -5y = -20 - 4x
              <u>-5y</u> = <u>-4x - 20</u>
               -5         -5
                 y = ⁴/₅x + 4
The slope would be ⁴/₅.

Natasha had d dollars. She bought two ice creams which cost x dollars each. How much money does she have left?
Anit [1.1K]
M in this case stands for money, while d means dollars and x is the cost of the ice creams
m = d - x(2)

You spin a spinner, flip a coin, then spin the spinner again. Find the probability of spinning an odd number, flipping heads, th
vovangra [49]

Answer:

1/8

Step-by-step explanation:

you would multiply 5/10x1/2x5/1o. Since the spinner has 10 areas, 5 of them are odd and 5 are even and a coin has 2 sides, head or tails.

What is the future value of a R 75 000 deposit made every 6 months for 3 years using an annual rate of 10% compounded semi-annua
dolphi86 [110]

Answer:

The future value is: RS 132867.075

Step-by-step explanation:

Given

PV = 75000 --- present value

r = 10\% --- annual rate

n = 6 --- number of times compounded (3 years/ 6 months)

Required

The future value

This is calculated as:

FV =PV * (1 + r)^n

FV = 75000 * (1 + 10\%)^6

FV = 75000 * (1 + 0.10)^6

FV = 75000 * (1.10)^6

FV = 132867.075

<em>Hence, the future value is: RS 132867.075</em>
