5Red + 6Blue + 4 Black
Total = 5 + 6 = 4 = 15
Probality of Blue, Blue.
P(Blue) = 6/15 = 2/5
P(Blue, Blue) = (2/5)*(2/5) = 4/25
I think it’s a cause if just divide and multiply
Answer:
fat bit
fat old ugly
Step-by-step explanation:
<h3>Radius = 14cm</h3>
Step-by-step explanation:
Let O be the centre of the circle. Since P and S are the points of contact of tangents AD and DC respectively, OP ⊥ AD and OS ⊥ DC
Also, AD ⊥ DC (given), therefore, OPDS is a square.
BR = BQ = 27cm...(tangents from an external point to a circle are equal in length)
therefore, CR = CB - BR = (38 - 27)cm = 11cm
SC = CR = 11 cm...(tangents from an external point) therefore, DS = DC - SC = (25 - 11) cm = 14 cm.
therefore,
Radius of a circle = OP = DS = 14 cm...(therefore, OPDS is a square).
