12. In Europe, 88% of all households have a TV. 51% of all households have a TV and VCR. What is the probability that a househol
PSYCHO15rus [73]

Answer:

0.579  is the probability that a household has a VCR given they have a TV.

Step-by-step explanation:

We are given the following in the question:

Probability of all households have a TV = 88% = 0.88

P(T) = 0.88

Probability of all households have a TV and VCR = 51% = 0.51

P(T\cap V) = 0.51

We have to find the probability that a household has a VCR given they have a TV.

The conditional probability is given by:

P(V|T) = \displaystyle\frac{P(V\cap T)}{P(t)} = \frac{0.51}{0.88} = 0.579

0.579  is the probability that a household has a VCR given they have a TV.

Roman55 [17]

Answer:

a.\frac{1}{17}

b.\frac{1}{16}

Step-by-step explanation:

We are given that two cards are drawn are randomly selected from a standard 52- cards deck.

Total cards=52

Total number of spade cards=13

Probability=\frac{number\;of\;favourable\;cases}{total\;number\;of cases}

a.The probability of drawing two cards first card is spade and second card is spade without replacement =\frac{13}{52}\times \frac{12}{51}

The probability of drawing two cards first card is spade and second card is spade=\frac{1}{17}

b. The probability of drawing two cards first is spade and second card is a spade with replacement =\frac{13}{52}\times\frac{13}{52}

The probability of drawing two cards first is spade and second card is a spade with replacement =\frac{1}{16}
