In a family of four children, what is the probability of 2 boys and 2 girls? P (2 boys, 2 girls) = P(BBGG) + P(BGGB) + P(GGBB) + P(GBBG) + P(GBGB) + P(BGBG) = ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ + ½ ½ ½ = 6/8 (75%) .transparent { position: relative; } .transparent a { position: absolute; top: 0; left: 0; width: 800px; height: 250px; z-index: 100; } .transparent a::before { } @media only screen and (max-width: 600px) { .transparent a { height: 525px; width: 100%; max-width: 600px; } } Related Downloads Rating: N/A Views: 85 Contributor: Guest
