Each friend has a 30% chance to get a musical card. Design a simulation that can be used to estimate the probability that a friend who receives 2 greeting cards will receive at least one musical greeting card

The probability that a friend who receives 2 greeting cards will receive at least one musical greeting card is 0.3

Step-by-step explanation:

The probability of getting a musical card = P(A) = 30 % or 0.3

Therefore probability of not receiving a plain card = P(A)' = P(B) = 100-30  or 1- 0.3 = 0.7

The probability of receiving at least one musical card when two cards are given is

P(A)×P(A) +P(A)×P(B)-P(B)×P(B) =0.3×0.3+0.3×0.7 = 0.3

The probability of receiving at least one musical card = 0.3

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
