Answer:

2820 seats
aₙ = 3n + 9

Step-by-step explanation:

This is an AP with:

The first term a₁ = 12
Common difference d = 3
Number of terms n = 40

Number of the seats:

Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats

Formula of nth term:

aₙ = a₁ + (n - 1)d
aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
aₙ = 3n + 9

In a certain lottery game, 34 numbers are randomly mixed and 7 are selected. A person must pick all 7 numbers to win. Order is n

777dan777 [17]

Answer:

p(win)=0.00094

Step-by-step explanation:

-This is a factorial/combination question.

-The probability is calculated using the formula:

$p=\frac{x!}{_nC_x}\\\\$

Where:

$x$ is the number of successful picks

$n$ is the total number of picks

Therefore, we calculate the probability as follows;

$Pp=\frac{x!}{_nC_x}\\\\=\frac{7!}{_{34}C_7}\\\\=0.00094$

Hence, the probability of winning is 0.00094
