How do we know to use a binomial distribution here? Based on these three reasons:

Each event is independent. Each tire puncture is independent of any other puncture. The probability of puncture is constant at p = 0.00005 (there are four zeros between the decimal point and the 5).
There are a fixed number of trials. In this case, there are n = 10,000 trials.
There are two outcomes. Either a tire is punctured, or it is not punctured.

Answer:

Probability at least one car will get punctured: 0.39347

Step-by-step explanation:

B(10,000 , 0.00005)

P(X ≥ 1) = 1 - P(X = 0)

= 1 - (1 - 0.00005)^10,000

= 1 - (0.99995)^10,000

= 1 - 0.60652...

= 0.39347 (probability that at least one car will get punctured)

As you can tell P(X ≥ 1) as we have to solve for the probability that at least one car will get punctured. That is of course 1 - [ P(X = 0) ].

The Baker Family spent $28 on 5 tickets.

White raven [17]

Answer:

I cannot not give the correct solution, need more context. How many children are there, how many adults are in the family? So I will explain in my explanation.

Step-by-step explanation:

If more context were given, for example: 2 adults and 2 children.

Then the bakers would have bought 2 adult tickets for ___ each

Then the bakers would have bought 3 children's tickets for ___ each

So using what we know we can create an equation:

2A+3C=28,

meaning 2 adult tickets plus 3 children's tickets costs a total of $28.

So we divide 28 by 5, which is the total amount of tickets.

28/5=5.6

So to figure the cost of children's tickets multiply the cost by amount.

3*$5.6=$16.8, C=16.8

To figure out the cost of the adults tickets multiple the cost by the amount.

2*$5.6=$11.2, A=11.2

a) the bakers would have bought 2 adult tickets for 5.6 each.

b) the bakers would have bought 3 children's tickets for 5.6 each.

Help i will mark you brainliest!

Since x+y equals 5 that means x is 3 and y is 2 because 3+2=5. So now plug it in, 2(3)+3(2). Two multiplied by three is 6 and three times two is 6. So now it’s 6+6 which equals 12. So it’s 2(3)+3(2)=12
