Please help I will be very grateful for this. pls also explain it will really help.

Assuming the events "baby is a boy" and "baby has blue eyes" are independent, we simply multiply the given fractions to get (1/2)*(1/4) = 1/8

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
