3 Points] DETAILS MY NOTES JMOD 3.3 .072. Jse probability rules to find the probability that a child will have neither sickle-cell anemia nor sickle-cell trait if the following occurs. (Enter your answers as fractions.) (a) each parent has sickle-cell trait \( 1 / 4 \) (b.). one.parent.has sickle-cell trait' and the other parent has no sickle-cell gene Enter a fraction, integer, or exact decimal. Do not approximate.

One card is chosen at random from a standard deck of 52 playing cards. Find the probability of drawing a red king a jack of diamonds a picture card (i.e. king, queen or jack)

The probability that it will be sunny tomorrow is \( \frac{2}{9} \). If it is sunny, the probability that Siya plays rugby is \( \frac{8}{15} \). If it is not sunny, the probability that Siya plays rugby is \( \frac{4}{15} \) 9.2.1 Represent the above information on the tree diagram and indicate all the possible outcomes.

9.1 Given: \( P(A)=0,45 ; P(B)=y \) and \( P(A \) or \( B)=0,74 \). Determine the value(s) of \( y \) : 9.1.1 If \( A \) and \( B \) are mutually exclusive events. 9.1.2 If \( A \) and \( B \) are independent events.

A three-digit number is to be formed from the digits 1,6 and 8 . What is the probability that the number will:

The probability that it will be suminy tomorrow is \( \frac{2}{9} \), If it is sunny, the probability tha Siya plays rugby is \( \frac{8}{15} \). If it is not sumy, the probability that Stya plays rugby is \( \frac{4}{15} \) 9.2.1 Represent the above information on the tree diagram and indicate all the possible outcomes.
