P(both red)=(10/17)(9/16)
P(both blue)=(7/17)(6/16)
P(both same)= sum of above 2 = (90+42)/(16*17)=132/(16*17)=<span>0.485
coz both same means  both blue or both red

Answer:
1.) 90 ways
2.) 15,600 ways
3.) 24 ways
Step-by-step explanation:
1.)  Let's say   we are given 2 digits not equal to each other...The number of different orderings would be  2*1 = 2, or  if we wanted the number of ways to order 2 digits chosen :   10*9 = 90 ways
2.)   The number of ways to arrange 3 letters from 26 letters is:
26 Permutes 3  =    26! / (26 -3)!  =  26*25*24 = 15,600 ways to choose 3 letters in a certain order
3.) 4 different chores.  The number of ways to do them =  4*3*2 *1 = 24 ways
