snow_lady [41]

Answer:

Step-by-step explanation:

Overall probability = Probability1 *Probability2

Using the data you already have, you can fill it in as

0.35 = 0.48 * P2

Rearrange to isolate P2, by dividing both sides by 0.48, so

0.35/0.48 = P2

P2 = 0.7291666..., which rounded to two d.p is 0.73

So d)0.73 is correct

Lakshmi has 11 more20-rupee notes than 10-rupee notes. If she has Rs 550 in total, how many notes of each kind does she have?
olganol [36]

Answer:

10rupee notes are 11

20rupee notes are 22

Step-by-step explanation:

Let 10-rupee note be x

20-rupee note will be x + 11

The equation will be

10x + 20(x + 11) = 550

10x + 20x + 220 = 550

30x = 330

x = 330/30 = 11 = 10rupee notes

y = 11+11 = 22 = 20rupee notes
