Answer 1

Answer:

1. probability is a branch of mathematics that deals with calculating the likelihood of given enents occurence

Step-by-step explanation:

b.    x+y=5------1

      x-y=4-------2

by simplifyingit in elimination method,we get y=1/2

put y in eq 1

x=9/2

ans=y=1/2,x=9/2

c.royal=5*4*3*2*1

          =120 ways

Answer 2

Answer:

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur or how likely it is that a proposition is true. Probability is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility and 1 indicates certainty.

the various ways in which objects from a set may be selected, generally without replacement, to form subsets. This selection of subsets is called a permutation when the order of selection is a factor, a combination when order is not a factor.

x+y = 5

x-y = 4

=> x = 9/2 , y = 1/2

=>without repeatation Royal = 5! = 120

=> with repeatation = 5^5
