The probability that the 10th will be able to sit on his/her original seat when the 1st person has randomly changed his/her seat is 7/9
Probability :
In Mathematics, Probability stands for the ratio of the number of favorable outcomes to the total number of outcomes in a random experiment. It is used to predict how likely an event can happen.
Probability of an event,
P(E) = No of favorable outcomes / total number of outcomes
Here we have,
10 people always get on a bus in the same order and sit in the same places.
The 1st person has randomly changed his/her seat
Except for 1 remaining number of seats is 9
If 1st person changes his/her place with the remaining 9 seats the number of ways that 1st person can be seated is 9
In 9 ways 10th will be able to sit on his/her original seat when the 1st person is seated in 2 to 9 seats i.e 7 seats
Therefore,
The number of favorable outcomes that the 10th person will be able to seat in his/her original seat = 7
From the above observations,
The probability that the 10th will be able to sit on his/her original seat
= 7 / 9

Answer:
Graph (a)
Step-by-step explanation:
When we take x = 0 and replace in the given formula we get:
y = 0.5 (0.5)ˣ = 0.5 (0.5)⁰ = 0.5 · 1 = 0.5 and this corresponds to graph (a).
God with you!!!
Answer:
4/3
Step-by-step explanation:
6n - 4 = 3n + 8
6n - 3n = 8 + 4
3n = 4
n = 4/3
