In a relay race, the probability that team sapphire wins is 22%. in another unrelated relay race, the probability that team emerald wins is 47%. how many percent probability both teams lose their races?

P(sapphire wins) = .22
P(sapphire loses) = 1-.22 = .78
 
P( emerald wins) = .47
P( emerald loses) = 1- .47 = .53
 P ( sapphire loses & emerald loses ) = P( sapphire loses) * P(emerald loses) = 0.78*0.53 = 0.4134 

Which multiplied by 100 means 41.34%. I hope that this is the answer that you were looking for and it has helped you.

They both determine the exact age of rocks.
