Answer: There are only two sides in each coin that Olga flips. If the coin lands on heads or tails then both will have a different result as one of them will be revealed to Olga as the coin stops flipping. For example Jessica flips a coin and it lands on tails and heads will not be revealed.

Nat2105 [25]

Answer:

1. 5040

2. 20

Step-by-step explanation:

1. using the formula for permutation

nPr=n!/(n-r)!

10P4 = 10!/(10-4)!

=10*9*8*7*6!/6!

then we are left with

=10*9*8*7

=5040

2.using the formula for combination

nCr=n!/(n-r)!r!

6C3=6!/(6-3)!3!

=6*5*4*3!/3!3!

=6*5*4/3*2*1

=20
