Jand k are independent events. p(j | k) = 0.3. find p(j)

 The required value of P(J) is 0.3.

Step-by-step explanation:  Given that J and K are independent events and P(J | K) = 0.3.

We are to find the value of P(J).

We know that if A and B are two independent events, then

The conditional probability of event J given that K has already been occured is

Since J and K are independent events, we get

Therefore, we get

Thus, the required value of P(J) is 0.3.

it is a function because for every x value there is only one y value

for every x value there is only one y value

step-by-step explanation:

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
