Answer:

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

8)Reduce a las unidades indicadas: a)18 cm 3 a dm 3
lys-0071 [83]

Answer:

(a) 0.018 dm^3

(b) 20 x 10^15 ml^3

Step-by-step explanation:

a) 18 cm^3 to dm^3

1 cm = 0.1 dm

So,

1 cm^3 = 0.001 dm^3

So, 18 cm^3 = 18 x 0.001 dm^3 = 0.018 dm^3

b) 20 hl^3 to ml^3

1 hl = 100000 ml

So, 1 hl^3 = 10^15 ml^3

So,

20  hl^3 = 20 x 10^15 ml^3.
