2 coins means 4 outcomes 2 heads on 2 coins so the probability is 2/4

When two coins are tossed then its sample space is:- {HH , HT , TH , TT} Let us denote the event P(A) by the two heads when tossed. Total outcomes :- 4 As we have to find the probability of 2 heads so there is only and only one faveourable outcome. Favourable Favourable outcome :- 1 {HH} Probability of event P(A) = Favourable outcomes _____________________ Total outcomes Probability of event P(A) = 1 _ 4 So the probability of getting two heads when two coins are tossed is 1/4. HOPE IT HELPS YOU! REGARDS, SHUBHAM

Given In the adjacent figure AB||CD; CD || EF and y:z =3:7, find x.

y / z = 3 / 7

y = 3 / 7 z

CD is parallel to EF

y + z = 180 (alternate interior angle)

3/7 z + z = 180

3z + 7z / 7 = 180

10 z = 1260

z = 126 degree

So y = 3/7(126)

y = 54 degree

AB is parallel to CD

There is a transversal in between. We know that sum of interior angles of same side of transversal is supplementary. So

x + y = 180

x + 54 = 180

x = 180 - 54

x = 126 degree

AB is also parallel to EF and x = z.

Hence x = 126 degree

first make a line of 8cm and give them name B and C, then make 45degree at B then draw a long line from B and mark 3.5 at that line by measuring and mark that point as A then make perpendicular bisecter of AB and BC then join A andC from where bisecters meet. try it once
