Probability of an event = No. Of favourable occurrences / Total no. Of occurrences of all possible events Let 'n' be the total no. Of times the coin is tossed. Given probability of success of a head appearing = 0.4 Given the no. Of times 'head' appeared = 24 So, 0.4 = 24 / n n = 24 / 0.4 So, n = 60.

Answer of n =60, since p(h)=0.4 , and n=24= total no of head appearances, then we get equation , 0.4 n = 24 / n, solving fr n total appearances 0.4 n =24 .. eq (1) or 4n =240 or n=240/4=60 total appearances , is the required answer .. Dr K S Velmurugan Quantitative methods Teacher Pondicherry

Factorize: (m * n) + (p * n) + m * q + p * q?
Step 1: Group terms like they’re forming a band: Step 2: Factor common stuff: Step 3: Combine like a Bollywood duo:
Jagabandhu
Solve : x + y = 18; y + z = 12; z + x = 16
Let x+y=18---(1), y+z=12---(2),z+x=16---(3) Solving (2)-(3) we get y+z-z-x=12-16 y-x=-4--(4) Solving (4)+(5) we get x+y+y-x=18-4 2y=14 y=14/2=7 Substitute y value in (1) x+7=18 x=18-7=11 Substitute x value in (3) z+11=16 z=16-11=5 x=11, y=7, z=5
