Dogs are inbred for such desirable characteristics as blue eye color, but an unfortunate by-product of such inbreeding can be th

sesenic [268]

Answer:

The probability that the dogs are blue eyed and deaf is 13.02%.

Step-by-step explanation:

We are given the following information in the question:

P(Blue eyes) = 31%

P(Deaf) = 38%

P(Deaf | Blue eyes) = 42%

Formula for conditional probability:

$P( A|B) = \displaystyle\frac{P(A \cap B)}{P(B)}$

Now, let A be the event where the dog is deaf and B be the the event where dog is blue eyed.

$P( \text{ Deaf}|\text{Blue eyes}) = \displaystyle\frac{P( \text{Deaf} \cap \text{Blue eyes})}{P(\text{Blue eyes})}\\\\0.42 = \displaystyle\frac{P( \text{Deaf} \cap \text{Blue eyes})}{0.31}\\\\P( \text{Deaf} \cap \text{Blue eyes}) = 0.42\times 0.31 = 0.1302 = 13.02\%$

Hence, the probability that the dogs are blue eyed and deaf is 13.02%.

An angle measures 84° What is the measure of its supplement?

Lesechka [4]

<u>Answer:</u>

Supplement of 84° is 96°

Complement of 54° is 36°

<u>Step-by-step explanation:</u>

1<u>) A supplementary angle is two angles that add up to 180°</u>

so to find the supplement of 84° ⇒ 180°- 84° = 96°

2) <u>A complementary angle is two angles that add up to 90°</u>

so to find the complement of 54° ⇒ 90°- 54° = 36°

lesantik [10]

Answer:

1/52

Step-by-step explanation:

There is only one of each type of card in each suit.

P(card is a diamond) = 13/52

P(card is a diamond + king) = (13/52)×(1/13) = (13/676) = (1/52)
