The total number of alphabets are 26.

The total number of vowels are 5.

Th repetition is allowed.

The possible outocme for all to be vowels are,

$PO=5^4$ $PO=625$

The total outcome is,

$TO=26^4$

Therefore, the probability that all 4 will be vowels ,

$P=\frac{625}{456976}$ $P=0.00137$

The probability is 0.137 %.
