Please help QUICKLY! please explain your answer, please give the correct answer
alisha [4.7K]

Answer:

  • 0: 0.7056
  • 1: 0.2688
  • 2: 0.0256

Step-by-step explanation:

When events are independent, the probability of some sequence of them is the product of the probabilities of the individual events in that sequence.

The probability of a child having spina bifida is 16% = 0.16, so the probability that the child will not have the condition is 1 - 0.16 = 0.84. The probability that 0 of 2 children will have spina bifida is ...

  p(0 for 2) = p(0 for 1)×p(0 for 1) = 0.84×0.84 = 0.7056

__

There are two ways that 1 of 2 children can have spina bifida: either the first one does, or the second one does. These are mutually exclusive conditions, so their probabilities add:

  p(1 for 2) = p(1 for 1)×p(0 for 1) +p(0 for 1)×p(1 for 1) = 0.16×0.84 +0.84×0.16

  p(1 for 2) = 0.2688

__

There is one way both children can have spina bifida:

  p(2 for 2) = p(1 for 1)×p(1 for 1) = 0.16×0.16 = 0.0256

__

In summary, our probability distribution is ...

  p(X=0) = 0.7056

  p(X=1) = 0.2688

  p(X=2) = 0.0256

Select all the expressions that are greater than 1.
anygoal [31]

Answer:

Expressions greater than 1 are:

5 \div  \frac{9}{10}

2 \frac{3}{2}  \div  1\frac{3}{5}

Step-by-step explanation:

5 \div  \frac{9}{10}

= 5 \times  \frac{10}{9}

=  \frac{50}{9}

= 5.55

___________________________________________

=  \frac{3}{5}  \times  \frac{1}{6}

=  \frac{1}{5}  \times  \frac{1}{2}

=  \frac{1}{10}

= 0.1

________________________________________

\frac{4}{5}  \div  \frac{3}{7}

=  \frac{4}{5}  \times  \frac{3}{7}

=  \frac{12}{35}

________________________________________

2 \frac{3}{5} \div 1 \frac{3}{5}

=  \frac{13}{5}  \div  \frac{8}{5}

=  \frac{13}{5}  \times  \frac{5}{8}

=  \frac{13}{8}

= 1 \frac{5}{8}

________________________________________

\frac{12}{5}  \div  \frac{13}{5}

=  \frac{12}{5}  \times  \frac{5}{13}

=  \frac{12}{13}
