Answer:

a) 0.06 = 6% probability that a person has both type O blood and the Rh- factor.

b) 0.94 = 94% probability that a person does NOT have both type O blood and the Rh- factor.

Step-by-step explanation:

I am going to solve this question treating these events as Venn probabilities.

I am going to say that:

Event A: Person has type A blood.

Event B: Person has Rh- factor.

43% of people have type O blood

This means that $P(A) = 0.43$

15% of people have Rh- factor

This means that $P(B) = 0.15$

52% of people have type O or Rh- factor.

This means that $P(A \cup B) = 0.52$

a. Find the probability that a person has both type O blood and the Rh- factor.

This is

$P(A \cap B) = P(A) + P(B) - P(A \cup B)$

With what we have

$P(A \cap B) = 0.43 + 0.15 - 0.52 = 0.06$

0.06 = 6% probability that a person has both type O blood and the Rh- factor.

b. Find the probability that a person does NOT have both type O blood and the Rh- factor.

1 - 0.06 = 0.94

0.94 = 94% probability that a person does NOT have both type O blood and the Rh- factor.

Find the integer that makes this subtraction statement true -3 - ? = -5

Elenna [48]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{2}}}}}$

Step-by-step explanation:

Let the missing integer be x

Solve for x

$\sf{ - 3 - x = - 5}$

Move 3 to right hand side and change it's sign

$\dashrightarrow{ \sf{ - x = - 5 + 3}}$

The negative and positive integers are always subtracted but posses the sign of the bigger integer

$\dashrightarrow{ \sf{ - x = - 2}}$

Change the signs of both sides

$\dashrightarrow{ \boxed{ \sf{x = 2}}}$

Hope I helped!

Best regards! :D
