Answer:
20349.
Step-by-step explanation:
It is given that,
Total number of toys = 21
Number of toys to be selected = 5
Total number of ways to select 5 toys from 21 toys is
[tex]\text{Total ways}=^{21}C_5=\dfrac{21!}{5!(21-5)!}[/tex]
[tex]=\dfrac{21!}{5!(21-5)!}[/tex]
[tex]=\dfrac{21\cdot 20\cdot 19\cdot 18\cdot 17\cdot 16!}{5\cdot 4\cdot 3\cdot 2\cdot 1\cdot 16!}[/tex]
[tex]=20349[/tex]
Therefore, the required ways are 20349.
