Answer:
Third and sixt option
Step-by-step explanation:
Applying the distributive property:
(b-2c)(-3b+c)=b(-3b)+b(c)-2c(-3b)-2c(c)
(b-2c)(-3b+c)=-3b^2+bc+6bc-2c^2
Adding like terms:
(b-2c)(-3b+c)=-3b^2+7bc-2c^2
The simplified product has 3 terms (first and second option are not true)
The simplified product has a degree of 2 (third option is true)
The simplified product, in standard form, has exactly 2 negative terms: -3b^2 and -2c^2 (sixth option is true)
Answer:
The probability that she chooses 3 spades and 2 cards that are not spades is
0.08154
Step-by-step explanation:
52 deck cards have 13 spades , 13 clubs , 13 diamond, 13 hearts
spades = 13
Non spades = 39
Selecting 3 spades = 13C3 (Using combination)
selecting 2 spades = 39C2
in total 5 cards are drawn = 52C5
Probability of drawing 5 cards (3spades+2 non spades)
=
= 0.08154
