Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, on
Iteru [2.4K]

Answer:

P(X_i=2) =\dfrac{1}{6}

P(X_i=-1) =\dfrac{5}{6}

Step-by-step explanation:

Given the numbers on the chips = 1, 1, 3 and 5

Miguel chooses two chips.

Condition of winning: Both the chips are same i.e. 1 and 1 are chosen.

Miguel gets $2 on winning and loses $1 on getting different numbers.

To find:

Probability of winning $2 and losing $1 respectively.

Solution:

Here, we are given 4 numbers 1, 1, 3 and 5 out of which 2 numbers are to be chosen.

This is a simple selection problem.

The total number of ways of selecting r numbers from n is given as:

_nC_r = \frac{n!}{r!(n-r)!}

Here, n = 4 and r = 2.

So, total number of ways = _4C_2  = \frac{4!}{2!\times 2!} = 6

Total number of favorable cases in winning = choosing two 1's from two 1's i.e. _2C_2 = \frac{2!}{2! 0! } = 1

Now, let us have a look at the formula of probability of an event E:

P(E) = \dfrac{\text{Number of favorable ways}}{\text{Total number of ways}}

So, the probability of winning.

P(X_i=2) =\dfrac{1}{6}

Total number of favorable cases for -1: (6-1) = 5

So, probability of getting -1:

P(X_i=-1) =\dfrac{5}{6}

How do you think you could simplify f(x) + g(x) if f(x) = 3x + 2 and g(x) = 4x?
NARA [144]

Step-by-step explanation:

f(x) = 3x + 2

g(x) = 4x

= f(x) + g(x)

= 3x + 2 + 4x

= (3 + 4)x + 2

= 7x + 2

(f+g)(x) = 7x + 2
