Correct option is C) Porifers

1. In case of semiconductors, there is one missing electron from one of the covalent bonds.  2. The absence of electron leaves an empty space called as hole; each hole carries...

Correct option is (B) equally likely When an unbiased coin is tossed then Probability of getting head is P(H) \(=\frac12\) and Probability of getting tail is P(T) \(=\frac12.\) Hence, getting a head when an unbiased coin is tossed...

Correct option is (C) 1 When an unbiased coin is tossed then possible outcomes are S = {H, T}. \(\therefore\) P(H) = \(\frac12\) & P(T) \(=\frac12\) \(\therefore\) P(H) + P(T) \(=\frac12+\frac12=1\) Hence, sum of probabilities of getting a head...
