/_A and /_B are vertical angles. If m_A = (2x – 4) and mZB = (x + 1)º,then find the value of x.

Answers

1. Set each equation to each other. 2x-4=x+1
2. Subtract x from 2x. 2x-x-4=x-x+1
3. Add 4 to both sides. x-4+4=1+4
4. Answer to value of x=5.

In a game of poker a hand of five cards is dealt to each player from a deck of 52 cards. find the probablility of a hand containing a spade flush.

Answers

Answer:

0.00597

Step-by-step explanation:

Given,

Total number of cards = 52,

In which flush cards = 20,

Also, the number of spade flush cards = 5,

Since,

\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}

Thus, the probability of a hand containing a spade flush, if each player has 5 cards

=\frac{\text{Ways of selecting a spade flush card}}{\text{Total ways of selecting five cards}}

=(^(20)C_5)/(^(52)C_5)

=((20!)/(5!15!))/((52!)/(5!47!))

=(15504)/(2598960)

= 0.00597
