A coin is tossed 500 times and we get heads : 285 times and tails : 215 times When a coin is tossed at random , what is probability of getting (i) a h

Correct Answer - `(63)/(100)`

Correct Answer - `(i) 1/6 (ii) 1/3 (iii) 1/2 (iv) 1/2 (v) 1/3 (vi) 1/3`

Correct Answer - `(i) 3/8 (ii) 3/8 (iii) 7/8 (iv) 1/2 (v) 7/8`

Correct Answer - (i) 0.28 (ii) 0.4 (iii) 0.32

Given that \(\vec a, \vec b\) and \(\vec c\)are unit vectors. i.e., |\(\vec a\)| = |\(\vec b\)|  = |\(\vec c\)| = 1 And \(\vec a\) + \(\vec b\) + \(\vec c\) = \(\vec 0\) Then \((\vec a+\vec b+\vec c).(\vec a+\vec b+\vec c)=\vec 0.\vec...

Correct option is (B) 1/4 If two identical coins are tossed, then possible outcomes are S = {HH, HT, TH, TT}. Let event E be event of getting 2 heads. \(\therefore\) E = {HH} \(\therefore\) n(E)...

Correct option is (C) 7/8 If three coins are tossed then possible outcomes are S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} \(\therefore\) Total outcomes is n(S) = 8 Let event E...

Correct option is (B) 1/4 If two coins are tossed then possible outcomes are S = {HH, HT, TH, TT} Let event E = Getting two heads = {HH} \(\therefore\) n(E) = 1 & n(S)...
