Answer:
1/4669920
Step-by-step explanation:
First if all, when repetition is mot allowed, we use Permutation to get the number of possible outcomes as follows;
P(n, r) = n!/(n - r)!
Now, the order is important since the first, second, third and fourth prizes are different.
Thus, we need to define the Permutation.
We need to select 4 winners of the 48 people.
Thus, n = 48 and r = 4
Thus;
P(48,4) = 48!/(48 - 4)!
P(48,4) = 4669920
Now, probability is the number of favourable outcomes divided by number of possible outcomes
Thus,
Probability = 1/4669920
Hi there!
The Eqn. is :-
1.5 (x + 4) - 3 = 4.5 (x - 2)
1.5x + 6 - 3 = 4.5x - 9
Combining the like terms :-
1.5x - 4.5x = - 9 - 6 + 3
- 3x = - 15 + 3
- 3x = - 12
x =
x = 4
Hence, the required answer is → x = 4
~ Hope it helps!
