Latricia determines that the probability of spinning an even number and then a 3 on the spinner below is 34 which best describes the accuracy of Latricias solut class=

Respuesta :

Answer:

Latricia’s solution is inaccurate. Her solution describes the probability of spinning an even number or a 3 in the same spin.

Step-by-step explanation:

Answer with explanation:

Number on the Spinner are ={1,2,3,4}=4 in number

A= Spinning an even number

B= 3 on the spinner

Probability of an event

                           [tex]=\frac{\text{Total favorable outcome}}{\text{Total possible outcome}}[/tex]

Probability of getting an even number

             = Either 2, or 4 from the set of 4 numbers.

             [tex]=\frac{2}{4}\\\\=\frac{1}{2}[/tex]

 Probability of getting 3 on the spinner

           [tex]=\frac{1}{4}[/tex]

→A ∩ B=Getting an even number  ∩  3 on the Spinner

    ={2,4} ∩ {3}

    = 0

P (A ∩ B )=0

→→P (A ∩ B)=  Probability of spinning an even number and then a 3 on the spinner

As two events are mutually exclusive,that is A and B are disjoint.

So, P ( A∩B)=0

It should be,

→P(A ∪ B)   =P(A) + P (B)- P (A ∩ B)

 [tex]=\frac{2}{4}+\frac{1}{4}\\\\=\frac{3}{4}[/tex]

Latricia is Incorrect.

Option B

Latricia’s solution is inaccurate. Her solution describes the probability of spinning an even number or a 3 in the same spin.
