Maria isn't correct of this. Adding these will get you 82960 (You add the numbers) She must have miscalculated.
905 = 9 hundreds + 0 tens + 5 ones
or 8 hundreds, 10 tens, 5 ones
425 = 4 hundreds, 2 tens, 5 ones
8 hundreds, 10 tens, 5 ones
4 hundreds, 2 tens, 5 ones
---------------------------------------subtract
4 hundreds, 8 tens, 0 ones = 480......(905 - 425 = 480)
Answer:
Step-by-step explanation:
A.
P=(219/800)×(218/799)≈0.0747≈0.075
B.
800-219=581
P=(581/800)×(580/799)≈0.527
c.
P( 1 think role models and one thinks not role models)+P(both thinks they are role models)=(219/800)×(581/799)+(219/800)×(218/799)=(219×581+219×218)/(800×799)
=[219(581+218)]/(800×799)
=(219×799)/(800×799)
=219/800
=0.27375
=0.274
27 pots..... I think. You have to divide the 81 in 81/4 by 3.
