(5p*3p) + (5p*4) + (-7*3p) + (-7*4) =

15p² + 20p -21p - 28 =

15p²-p -28 =

A - drawing a red 8

B - drawing an 8

$P(A|B)=\dfrac{P(A\cap B)}{P(B)}\\\\ |\Omega|=52\\ |A\cap B|=2\\ |B|=4\\\\ P(A \cap B)=\dfrac{2}{52}=\dfrac{1}{26}\\ P(B)=\dfrac{4}{52}=\dfrac{1}{13}\\\\ P(A|B)=\dfrac{\dfrac{1}{26}}{\dfrac{1}{13}}=\dfrac{1}{26}\cdot13=\dfrac{1}{2}$

Identify the double displacement reaction.

Anit [1.1K]

A double replacement reaction occurs when the ionic parts of two ionic compounds are exchanged.

Reaction 1 results in a product which is a single compound. No ionic parts are exchanged.

Reaction 3 results in one compound being separated into its elemental parts. No ionic parts are exchanged.

Reaction 4 has two reactants, but Pb is an element and not an ionic compound. No ionic parts are exchanged.

Hence, the answer is Reaction 2. Both NaBr and Ca(OH)2 are ionic compounds. Br - is the anion in NaBr, and (OH)2 is also an anion. Ionic parts are exchanged.
